Tallow Mayo Recipe: Rich and Velvety Homemade Emulsion

There’s a reason chefs swear by tallow for mayonnaise—it creates an unmatched richness that store-bought versions can’t touch. This homemade emulsion delivers a velvety texture with a depth of flavor that elevates sandwiches, dressings, and dips to new heights.

I’ve spent years refining this method, balancing the fat content and emulsification process to ensure a stable, creamy result every time. The key is patience and precision, allowing the ingredients to come together into a smooth, luxurious spread.

Unlike traditional mayo, this version uses rendered beef fat for a robust, savory note that pairs beautifully with grilled meats and roasted vegetables. Its versatility makes it a staple for both everyday meals and special occasions.

Once you try it, you’ll never go back to commercial options. Here’s how to make it perfectly.

Ingredients for Tallow Mayo

Eight ingredients transform into a luxurious, velvety emulsion that redefines mayonnaise.

The tallow is non-negotiable here. Source from a trusted butcher or render your own from beef suet—look for grass-fed for the cleanest flavor. It must be fully cooled to room temperature before emulsifying, or it’ll separate. I recommend Fatworks brand if you’re not rendering yourself. The egg yolks act as the primary emulsifier, so use the freshest you can find for maximum stability.

No rendered tallow? Lard works in a pinch, though the flavor profile shifts. For a neutral taste, avocado oil at a 1:1 ratio is the closest substitute, but you’ll lose that signature depth. The Dijon can be swapped for whole-grain mustard at the same amount, and apple cider vinegar can replace the white wine vinegar. Skip the water if your emulsion is already perfect—it’s just a safety net.

Store in an airtight jar in the fridge for up to 2 weeks. The tallow will firm up when cold, so let it sit at room temperature for 10-15 minutes before using. Not suitable for freezing—it’ll break the emulsion. Always use a clean, dry spoon to prevent contamination.

Step-by-Step Instructions for Tallow Mayonnaise

Master the emulsion technique for a rich, velvety condiment with professional results.

Step 1: Prepare the Base Emulsion

In a food processor or immersion blender cup, combine the 2 whole Large Egg Yolks, 1 tbsp Dijon Mustard, 1 tbsp White Wine Vinegar, 1 tbsp Lemon Juice, 0.5 tsp Fine Sea Salt, and 0.25 tsp Freshly Ground Black Pepper.

Pulse until the mixture is smooth and pale yellow. The mustard acts as a natural emulsifier, while the vinegars provide the necessary acidity to balance the richness of the tallow. Ensure all ingredients are fully incorporated before proceeding.

Step 2: Begin the Slow Drizzle of Tallow

With the processor running or while blending continuously, start adding the 1 cup Rendered Beef Tallow in a very thin, steady stream. The tallow must be melted and cooled to room temperature—this is critical for proper emulsification.

Add no more than a few drops at a time initially, allowing the mixture to thicken slightly before increasing the flow. This gradual incorporation is key to creating a stable emulsion that won’t separate.

Step 3: Achieve Full Emulsification

Once about half of the tallow has been incorporated and the mixture begins to thicken and lighten in color, you can increase the drizzle slightly. The mayonnaise should start to take on a creamy, velvety texture.

If the mixture appears too thick or the processor struggles, add the 1 tsp Filtered Water to loosen it slightly. This ensures a smooth, consistent texture without breaking the emulsion.

Step 4: Finish and Adjust Consistency

After all the tallow has been added, continue blending for an additional 10-15 seconds to ensure the mayonnaise is fully emulsified. The final product should be thick, glossy, and pale ivory in color.

Taste and adjust seasoning if needed. If the mayonnaise is too thick, incorporate a tiny splash of water, one teaspoon at a time, until reaching your desired consistency. Store in an airtight container in the refrigerator for up to 1 week.

Essential Equipment for tallow mayo

Immersion Blender

An immersion blender is my go-to for this recipe because it lets you control the emulsion with precision. I use a Breville Control Grip—its narrow blending cup is perfect for small batches. The key is keeping the blade submerged while drizzling the tallow slowly.

Food Processor

A standard food processor works just as well for larger quantities. I recommend a Cuisinart 14-cup for its reliability. The feed tube makes it easy to drizzle the tallow in a thin, steady stream while the blade runs continuously.

Whisk and Bowl

If you prefer a hands-on approach, a balloon whisk and a deep, narrow bowl will do the job. I like OXO’s stainless steel whisk for its comfortable grip. This method requires more elbow grease but gives you complete control over the emulsification process. 💪

Measuring Tools

A liquid measuring cup with a spout is essential for drizzling the tallow. I use Pyrex’s 1-cup measure—it pours smoothly and has clear markings. For the egg yolks, a small digital scale ensures accuracy, though volume measurements work fine here.

Storage Containers

Once finished, transfer your mayo to an airtight glass jar for storage. I prefer Ball Mason jars with wide mouths—they’re easy to clean and allow for simple scooping. A small silicone spatula helps scrape every last bit from the blender or processor. 🔥
