Guaranteed to render you speechless.
Often, a recipe will tell you to “render your bacon,” which sounds intimidating but is really simple.
All it means is to cook your bacon slowly over low or medium heat, so that all the fat has a chance to melt while the meat crisps. To render bacon. get a cast iron or stainless steel skillet big enough to hold all of the bacon you're rendering without crowding it. Heat the skillet over low heat and add bacon to the pan (no need to add oil.) If you're using pre-sliced bacon, cook the strips whole; If you're using slab bacon, cut it into 1/4-inch cubes. Cook it slowly, until the bacon is crisped and most of the fat is liquid.

Use it immediately, or store it in an airtight container in the refrigerator for up to a month.
Some recipes, like pie crust or cookies, will call for cold or room temperature bacon fat, which means that the fat will be solid and you'll cut or beat it into the other ingredients. Other recipes, like sauces or soups, call for you to heat the bacon fat and use it as cooking fat for other ingredients, which means either melting your cold, pre-rendered bacon fat, or using warm, just-rendered bacon fat.
