What Is Beef Tallow?

Introduction

What is beef tallow? Beef tallow is a natural fat made by slowly rendering beef suet—the firm fat found around a cow’s kidneys. While it’s been used for generations in cooking and soap making, it’s also become a popular ingredient in handcrafted skincare.

At Resting Beef Face, we start with locally sourced grass-fed beef suet and render our own tallow before it becomes part of our Face Balms and Body Butters. In this article, we’ll explain what beef tallow is, how it’s made, and why we choose to use it.

Step 1: What Is Beef Suet?

Everything begins with beef suet—the firm fat found around a cow’s kidneys. Unlike softer fat from other areas of the animal, suet has long been prized for rendering because of its clean, firm structure.

After sourcing our beef suet locally, it’s trimmed and broken into smaller pieces to help it render evenly.

Every batch starts here.

Step 2: How Beef Tallow Is Made

Once the suet has been prepared, it’s placed into a slow cooker where gentle, consistent heat begins the rendering process.

Rendering isn’t about cooking the fat quickly. It’s about patience.

As the suet slowly warms over several hours, the pure fat gradually separates from moisture and connective tissue. This slow approach helps create a clean, stable tallow that’s ready for the next stage.

Step 3: Filtering the Freshly Rendered Tallow

When rendering is complete, the tallow is still a clear golden liquid.

At this stage, it’s carefully filtered through layers of cheesecloth to remove any remaining solids.

Filtering is one of the most satisfying parts of the process. Watching the warm tallow pass through the cloth leaves behind a beautifully clean ingredient that’s ready to cool.

Step 4: Cooling Into Tallow

Freshly rendered tallow doesn’t stay golden for long.

As it cools, it naturally transforms into the creamy, pale tallow that’s used throughout our skincare collection.

This colour change is completely natural and simply reflects the fat returning to a solid state.

What began as raw beef suet has now become clean, handcrafted tallow.

Step 5: From Tallow to Skincare

Once our tallow has cooled, it becomes the foundation of our formulations.

Our Face Balm is intentionally simple, combining handcrafted tallow with castor oil to create a rich, water-free moisturizer. Our Lavender Face Balm follows the same minimalist formula with the addition of lavender essential oil.

Our Body Butters use the same handcrafted tallow but are formulated differently. By adding ingredients such as coconut oil, we’re able to create a lighter, whipped texture that’s designed specifically for full-body hydration.

Rather than using one formula for every product, each recipe is developed with its own purpose in mind.

Why We Make Our Own Tallow

Rendering our own tallow isn’t the quickest part of making skincare, but it’s one of the most important.

By starting with locally sourced grass-fed beef suet, we’re involved in every step—from preparing the raw ingredient to filtering the finished tallow before it ever reaches one of our mixing bowls.

For us, that process reflects the values behind Resting Beef Face: simple ingredients, thoughtful craftsmanship, and knowing exactly what goes into every batch.

Final Thoughts

When people see a jar of tallow skincare, they usually see the finished product.

What they don’t always see is the work that comes before it.

Preparing the beef suet.

Waiting patiently while it renders.

Filtering it by hand.

Watching it cool into creamy tallow.

These steps are all part of the process, and they’re the reason every batch begins with care long before it reaches your bathroom shelf.

Because at Resting Beef Face, quality doesn’t start in the jar.

It starts with the ingredient.
