Rendering tallow: here is how to do it

Rendering beef fat to make tallow has a few basic steps. The equipment required can be found in your kitchen. You can use the stovetop or a crockpot.

Step 1: prepare the fat

Cut the fat in small pieces and try to remove as much meat as possible. The smaller the pieces the better. You can grind it, if you have a meat grinder or use a food processor. If your fat is semi-frozen, it is much easier. You can avoid this step all together by asking the butcher to grind the beef fat first.

Step 2: begin to heat

Put the fat into a pan on a stovetop or crockpot and put it on a low heat. The fat will eventually turn into a liquid. It may take hours for the fat to melt down.

Step 3: cook the fat

Some liquid oil will start forming approximately one hour after the start of the process. Stir the fat around. Repeat that occasionally (about every 30 minutes or so) until all of the fat is melted completely.

 Consider taking a big spoon and smashing down the meat pieces so that the fat melts down much faster, but don’t let it stick to the pan. Once the fat is reduced to a liquid and golden brown, now it is time to strain the fat. You will need a metal strainer and a bowl to catch the fat. The strainer will catch any meat bits that were floating around in the fat, and the bowl will contain the melted down tallow which should be clear and yellow. Make sure that the bowl is made of a material that will not melt whenever you pour the fat into the bowl after straining it. So, this means do not use a plastic bowl. Let the tallow sit and cool down. Once it is cooled, it turns white and hard. Wash the block of tallow once it has dried and cooled down overnight in the refrigerator.

Storing Tallow

At this point, you can use the tallow to make soap. Each batch of tallow should last up to a year. Place the tallow in a plastic bag that is marked with the date it was rendered. It doesn’t have to be stored in the refrigerator, but it must be kept in an airtight container such as a mason jar.
