Tallow Soap - How To Render Fat To Create Tallow

Tallow is the a rendered form of animal fat, usually obtained from beef or mutton. It is an ingredient in many of the commercial soaps that are sold in supermarkets and one of the oldest ingredients used in soap making.

However, some people think that using tallow creates a soap that clogs pores and is damaging to the skin, which prompted a lot of soap makers and consumers to shun it. But actually, it’s the chemical additives added to commercial soaps that makes them harsh on our skin.

While a lot of people prefer to use vegetable oils when making soap, using tallow also has some advantages. Tallow soap are known to produce a nice and creamy lather and a hard and long-lasting soap. Aside from this, it’s relatively inexpensive and easy to obtain. When combined with vegetable oils, it can create fantastic soap products.

When creating tallow soap, and you’re using beef fat as an ingredient, you will need to render it to make it suitable for soap making. Here are instructions on how to render beef fat to create tallow:


5 pounds of beef fat - chopped into really tiny pieces or ground
5 tbsps salt



A large pot
A large bowl
A sieve
A large mixing spoon
Paper towels



  1. Put the beef fat in a large pot. Add enough water to cover the fat. Add in the salt.

  2. Boil the mixture over medium to high heat, then reduce to a simmer. Stir often.

  3. After about 30 minutes of simmering, you’ll notice the meat has cooked and turned brown. This tells you that you’ve melted all the fat. Simmering time depends on how small you were able to grind your beef fat. The smaller you started with, the fshorter the simmering time required.

  4. Drain the liquid and transfer to a large bow. Use the sieve t take out all the pieces of meat.

  5. Let the liquid cool at room temperature. You will observe that the melted tallow will rise to the surface.

  6. Transfer the bowl of cooled melted tallow to the refrigerator (not the freezer) and allow to cool overnight.

  7. You’ll know it’s ready when you see a solid white disc of tallow when you take the bowl out of the refrigerator. Using a knife, carefully pry out the rendered tallow. What’s left in your bowl will be a gray, gelatinous liquid. Dispose of this liquid properly.

  8. On the portion of the tallow facing the gelatinous liquid, you may see some loose pellets of fat. Using a paper towel, wipe these off and wash the rest under some running water.

  9. You’re now ready to use your tallow for soap making. To store the ones you don’t need yet, place them in freezer bags and label properly with the date when they were created. They will keep for about a year in the freezer.
