Add beef trimmings to a stock pot or Dutch oven. You'll want to use at least two pounds of trimmings
If using the stove, place the burner on a low heat setting. You want slow and low, anything too hot, or a rolling boil can burn the fat leading to a brown, funky taste
Allow the fat to render for at least thirty minutes, then stir occasionally to ensure all the bits are evenly distributed and are being heated evenly
Keep an eye on the pot! The last thing you want is a rolling boil as it can lead to an inferior product.
Rendering the fat into a clear liquid will depend on how much trimmings you used, but this process can typically take between 2-4 hours
Once the liquid is ready, it's time to get ready to strain it
There are many methods out there, but we like to double strain it, first using a mesh strainer, and then again using cheese cloth to ensure we have removed all the impurities
When straining ensure that you are using a heat resistant dish that can accommodate the hot beef fat liquid
Once the beef fat is strained - you now have tallow! The tallow is ready to be used, but we like to funnel it into a mason jar for long term storage.
Once the beef tallow has cooled it will become a a cloudy white substance that solidifies - almost like butter.
