For centuries, beef tallow was a cornerstone of global cuisine. Ancient Romans used it to preserve meat and fry food. Medieval Europeans relied on it for cooking, candle-making, and even leather conditioning. In early America, tallow wasIndispensable—settlers used it for everything from pie crusts to waterproofing boots.

In the 20th century, tallow had nearly disappeared from kitchens. Flawed nutritional studies demonized saturated fats, and industrial seed oils took their place. Only now, as modern science reevaluates dietary fats, is tallow reclaiming its rightfulrole in culinary traditions.

Beef tallow is rendered fat, primarily sourced from suet—the dense fat surrounding a cow’s kidneys and loins. Unlike lard (pig fat), tallow has a firmer texture and a higher smoke point, making it ideal for high-heat cooking.

The rendering process is simple but precise: suet is slowly melted at low heat, strained to remove impurities, and cooled into a smooth, shelf-stable fat. Properly rendered tallow can last up to a year at room temperature, a testament to itsstability.
The Nutritional Benefits of Tallow

Emerging research challenges old assumptions about saturated fats. Beef tallow contains a balanced profile of saturated and monounsaturated fats, including stearic acid,which may support healthy cholesterol levels. It’s also rich in conjugated linoleic acid (CLA), a fatty acid linked to reduced inflammation and improved metabolism.

Additionally, tallow provides fat-soluble vitamins A, D, E, and K2—essential for immune function, bone health, and skin vitality. Grass-fed tallow offers even higher concentrations of these beneficial compounds.

Tallow vs. Industrial Seed Oils

Unlike highly processed vegetable oils, tallow is a whole food. Industrial seed oils—such as soybean, corn, and canola oil—are often extracted with chemical solvents and are prone to oxidation, especially at high temperatures. Tallow, with its smoke point of 400°F or higher, remains stable under heat, reducing the formation of harmful compounds.

The shift from traditional fats like tallow may have contributed to modern health challenges. Reintroducing it into our diets could be a step toward more nourishing, ancestrally aligned eating.

Cooking oils are fundamental to culinary practices worldwide, bringing unique flavor, texture, and nutritional profile. The variety of cooking oils available today is vast, ranging from traditional options like olive oil and butter to more modern choices like avocado and coconut oil.

One of the most widely recognized cooking oils is olive oil, particularly extra virgin olive oil. This oil is appreciated for its rich flavor and high monounsaturated fats, which are popular and support heart health by reducing harmful cholesterol levels. Olive oil is ideal for salad dressings, low to medium-heat cooking, and drizzling over finished dishes. However, its low smoke point makes it less suitable for high-heat methods like deep-frying.

In contrast, refined olive oil has a higher smoke point and can handle more heat, though it lacks the robust flavor of its extra virgin counterpart. Another popular oil is coconut oil, which has gained a reputation for its unique composition of medium-chain triglycerides (MCTs).

The body metabolizes these fats differently, potentially providing a quick energy source. Coconut oil is solid at room temperature and has a distinct tropical flavor, making it a favorite in baking and sautéing. However, its high saturated fat content has sparked debate among health experts, with some cautioning against excessive consumption due to potential links to increased cholesterol levels.

Oils with high smoke points are essential for high-heat cooking methods like frying. With its mild flavor and impressive smoke point, Avocado oil is an excellent choice for searing, grilling, and roasting. It is also rich in monounsaturated fats and vitamin E, contributing to its heart-healthy profile.

Similarly, peanut oil, commonly used in Asian cuisine, is another high-smoke-point oil that adds a nutty flavor to stir-fries and deep-fried dishes. Its stability at high temperatures makes it a reliable option for frying.

Canola oil, derived from rapeseed, is another versatile option with a neutral taste and a moderate smoke point. It is low in saturated fat and contains a precious balance of omega-3 and omega-6 fatty acids, making it a heart-healthy choice for baking, sautéing, and frying.

Conversely, butter and ghee (clarified butter) are cherished for their rich, creamy flavors. Butter is a world staple in baking and other applications and adds depth to sauces and sautéed dishes, but its high saturated fat content should be used in moderation. With its lactose and casein removed, Ghee has a higher smoke point and is suitable for higher-heat cooking. It is also a key ingredient in many traditional Indian dishes.

Seed oils, such as sunflower, safflower, and grapeseed oil, are often praised for their light flavors and high smoke points. These oils are typically high in polyunsaturated fats, particularly omega-6 fatty acids.

Moderation in use and consumption is key when incorporating these oils into your diet. More importantly, continue to document yourself for better options.

Health considerations are paramount when choosing cooking oils. Oils high in unsaturated fats, such as olive, avocado, and canola oil, are generally considered healthier due to their potential to improve cholesterol levels and drastically reduce The risk of heart disease.

Trans fats, primarily found in partially hydrogenated oils, are particularly harmful and should be avoided altogether. They are linked to increased risks of heart disease and other chronic conditions. In addition to health, the environmental impact of oil production is an essential factor to consider.

Palm oil, for instance, is widely used in processed foods and has a high smoke point, but its selection and production are often associated with deforestation and habitat destruction. Opting for sustainably sourced palm oil or alternative oils can help mitigate these tragic environmental concerns.

Welcome back to Flavors and Knowledge, the podcast where we explore the art of cooking, the science of ingredients, and the joy of eating with the seasons. I’m your host, Chef Walter, and today we’re diving into the vibrant world of April’s produce. Spring is in full swing, and the kitchen is alive with possibilities. Whether you’re a seasoned home cook or just starting the season's flavors, this episode will inspire you to embrace the flavors of the season and make the most of what April has to offer.

April is such a special time in the culinary calendar. It’s a bridge between winter's hearty, comforting foods and the lush, abundant harvests of late spring. This month, we’re greeted with tender asparagus, sweet peas, peppery radishes, and theearthy elegance of artichokes. These vegetables are at their peak, and their flavors are unmatched.

Take asparagus, for example. When roasted with olive oil and sea salt, it becomes caramelized and tender, with a nutty sweetness that’s hard to resist. Or shave it raw into a salad for a crisp, refreshing crunch. And let’s not forget fresh peas—whether you’re shelling them or enjoying them in the pod,they add sweetness to risotto, pasta, or even a simple spring soup.

But April isn’t just about vegetables. This month, leafy greens like spinach, arugula, and watercress are also shining. These greens are packed with nutrients and bring a lively,peppery flavor to dishes. Arugula pairs beautifully with citrus segments and a light vinaigrette, while watercress can be blended into a zesty pesto or tossed into a potato salad for a peppery kick. With its versatility, Spinach can be sautéed with garlic as a quick side dish or folded into quiches and frittatas for a hearty breakfast.

Today, we’re diving into a topic raising concerns in the food world—microplastics. They’re tiny, they’re everywhere, and they’re making their way into our diets. So, let’s break it down into three essential things you need to know about microplastics.

Microplastics are tiny plastic particles, usually less than five millimeters in size. They come from various sources, including broken-down plastic waste, synthetic fibers from clothing, and even microbeads once used in personal care products.

Over time, plastics degrade due to sunlight, heat, and mechanical stress, breaking down into smaller and smaller particles. And here’s the kicker: once they’re in the environment, they don’t just disappear. They accumulate.

2. How Are Microplastics Getting Into Our Food?

Microplastics have infiltrated the food chain in ways we might not even realize. Studies have found them in seafood, bottled water, salt, honey, beer, and fresh produce.

Fish and shellfish ingest microplastics in the ocean, and when we eat them whole—like oysters or sardines—we’re also consuming those particles. But it doesn’t stop at seafood. Plastics in soil and water affect crops; even our packaging can shed microplastics into food. In short, we’re likely consuming plastic in small doses every day.

3. What Does This Mean for Our Health?

Now, this is where things get a bit murky. While research is ongoing, early studies suggest that microplastics could carry harmful chemicals, disrupt hormones, and even cause inflammation when they accumulate.

Scientists are concerned about long-term exposure, and while the exact risks aren’t entirely known, minimizing our intake of microplastics seems like a wise precaution.

What Can We Do About It?

As consumers and culinary professionals, we can take a few steps to reduce our exposure:

• Filter your water – Many microplastics are found in tap and bottled water so that a high-quality filter can help.

• Reduce plastic packaging – Opt for glass, stainless steel, or natural materials for food storage.

• Eat fresh, unprocessed foods – Packaged foods often contain microplastics from processing and packaging.

• Support sustainable practices – Reduce single-use plastics and support brands actively working to minimize plastic pollution.

This episode explores the family meat markets.

A family meat market typically refers to a small, often family-owned butcher shop or business that sells fresh, high-quality meats. These establishments are usually run by generations of the same family, emphasizing personalized service, expertise in meat cutting, and a connection to local communities. Unlike supermarket chains, family meat markets often source their products from local farms or trusted suppliers, focusing on freshness, quality, and sometimes unique or specialty cuts that might not be available elsewhere.

In 2025, family meat markets hold significance for several reasons, reflecting evolving consumer priorities:

1. Quality and Transparency: With growing awareness about food sourcing, many consumers prefer to know where their meat comes from. Family meat markets often provide transparency about their supply chain, offering grass-fed, organic, or antibiotic-free options that align with health and ethical concerns.
2. Support for Local Economies: Shopping at a family meat market keeps money within the community, supporting small businesses and local farmers rather than large corporations. This appeals to consumers who value sustainability and economic resilience.
3. Customization and Expertise: Unlike pre-packaged meats at big stores, family butchers can offer custom cuts, advice on preparation, and even recipes tailored to a customer’s needs. This hands-on service is a draw for food enthusiasts or those seeking a more personal shopping experience.
4. Sustainability and Ethical Choices: Many family meat markets prioritize sustainable practices, such as working with farmers who use humane and environmentally friendly methods. This resonates with consumers who are increasingly concerned about climate change and animal welfare.
5. Nostalgia and Trust: For some, these markets evoke a sense of tradition and trust that’s harder to find in impersonal retail chains. The relationship between butcher and customer can feel more authentic, fostering loyalty.

In today’s fast-paced, convenience-driven world, family meat markets cater to a niche but growing segment of consumers who prioritize quality, locality, and a human touch over mass-produced alternatives. They’re not just selling meat—they’re offering an experience and a story that resonates with those looking to reconnect with their food’s origins.

In this episode, Chef Walter explores the Purim Holiday.

Purim is a Jewish holiday that commemorates the saving of the Jewish people from a plot to annihilate them in the ancient Persian Empire, as recounted in the Book of Esther (Megillat Esther) in the Hebrew Bible. The story centers on Esther, a Jewish woman who becomes queen, and her cousin Mordecai, who helps thwart the plans of Haman, a high-ranking official who sought to destroy the Jewish population.

The holiday is celebrated with a festive and lively atmosphere. Key traditions include:

1. Reading the Megillah: The Book of Esther is read aloud in synagogues, typically twice—once on the evening of Purim and again the following morning. Listeners often use noisemakers (graggers) to drown out Haman’s name as a symbolic rejection of his evil intent.
2. Costumes: People, especially children, dress up in costumes, reflecting the theme of hidden identities in the story (e.g., Esther concealing her Jewish heritage initially).
3. Festive Meal (Seudah): A joyous meal is shared with family and friends, often accompanied by singing and drinking. It’s customary to drink alcohol until one can’t distinguish between "cursed be Haman" and "blessed be Mordecai" (though moderation is also encouraged).
4. Mishloach Manot: People send gifts of food or drink (at least two different types) to friends and neighbors, fostering community and goodwill.
5. Matanot La’evyonim: Gifts or charity are given to people experiencing poverty, emphasizing generosity and support for those in need.
6. Triangular Treats: A popular food associated with Purim is hamantaschen (meaning "Haman’s pockets" in Yiddish), triangular pastries filled with poppy seeds, fruit preserves, or other sweet fillings. Some interpret the shape as representing Haman’s hat or ears.

Purim falls on the 14th of Adar II in the Jewish calendar (or Adar I in a leap year for specific communities), which usually corresponds to late February or March in the Gregorian calendar. In 2025, Purim begins at sundown on March 13 and ends at sundown on March 14.

The holiday is both a celebration of survival and a reminder of resilience, often infused with humor and satire. It’s one of the most joyous occasions in the Jewish year!

Welcome back, friends, to another episode of Flavors andKnowledge, where we explore food, culture, and history from a chef’s perspective. I’m Chef Walter and today; we’re taking a journey through my home state of Rhode Island—the smallest state in the U.S. but one packed with a history as rich as its culinary traditions.

Don’t let its size fool you—Rhode Island has played an outsized role in shaping America’s past and present. It’s a place of rebellion, innovation, and culinary gems that deserve the spotlight. So, grab a coffee milk—our official state drink—and let’s dig in.

A Colony Built on Freedom

Rhode Island was founded in 1636 by Roger Williams, who dared to challenge the Puritan authorities in Massachusetts. He believed in religious freedom and individual liberties, something unheard of in those days. Instead of submitting to persecution, he struck out on his own and established Providence, a colony where all were welcome—well before the idea of the First Amendment was conceived.

The Ultimate Preservation Technique

Freezing is one of the best ways to preserve food. It locks in nutrients and extends shelf life without using preservatives or additives. However, not all frozen foods are created equal.

The speed of freezing matters—a lot. Flash-freezing, a process that rapidly freezes food at extremely low temperatures, helps retain texture, flavor, and nutrients. Have you ever better than slow freezing, leading to ice crystal formation and cellularbreakdown. Ever noticed a soggy, lifeless strawberry after thawing? That’s the slow freeze effect!

While fresh ingredients are always ideal, properly frozen foods can be a fantastic alternative when handled and stored correctly. So, let’s explore the pros and cons.
