Rendered pork fat is also called lard. Pig is a fatty animal. and that excess amount of fat is rendered down for a lot of different purposes. Lard is used in cooking and baking. Lard contrary to popular belief is an healthier alternative to margarine. Lard also is a good source for Omega 3. Lard has a high smoking point which makes it ideal for deep frying. Lard rendered for a longer time has a stronger porky smell and the color gets darker as it renders longer.
Lard extracted while its off white or with light yellow hue is not that porky in smell hence its more suitable for baking. Lard can be obtained from different kinds of fat the pig has namely backfat, belly fat and leaf fat. Lard from leaf fat doesnt have that porky smell.
Bellow is my recipe for a mild Lard extracted when it started to have a slight yellow hue. Which when chilled turned white, similar to unsalted butter. There are many who say you can extract the lard while it is milky. i havent done that myself as i think at that point the moisture isnt completely gone and the blood and tissue is still not cooked out complete, making it risky for storage and consumption
To be on the safe side my recommendation would be going for the light yellow hue while making sure there is no bubbling or sizzling. the crispy bits of fat called cracklings can be used in a number of dishes or as a snack or even as a treat for pets.
