What each ingredient does

Clean fat
It is the product: gentle heat melts out pure fat, leaving solids and impurities behind.

The step that matters

Boil until all the water has evaporated. Water must fully boil off before the fat can get hot enough to brown or burn. Any water left behind can spatter and shorten the fat's shelf life. Stirring occasionally keeps solids from scorching on the pan bottom.
