Cut the fat into small chunks, about the size of your thumb
Add small chunks to a crockpot and cover in water
Add a small handful of salt
Turn the crock pot on high and melt the fat until it is liquid, stirring ocassionally
Strain through a fine mesh sieve into a heat safe bowl to remove any remaining skin, cartilage, bone, etc.
Place the bowl in the fridge or freezer
Once the fat is solid and separated from the water, remove it and place on a clean cutting board
Scrape the bottom of the fat block to remove any brown bits, these are the impurities that have been drawn from the fat
Add the fat back to the cleaned crockpot with fresh water and salt.
Repeat steps 4-8 until the fat is completely white and you no longer need to scrape off any brown bits
Melt the fat down one more time but do not add any water or salt
After melting it, pour into molds and allow them to solidify in the freezer
Once solidified, remove the rendered tallow blocks from the molds and store in a freezer-safe bag in the freezer for long term storage.
Slice, weigh, measure, melt, and use as needed for all your tallow skincare and recipes!
