Cook the bacon in a large skillet. Once the bacon is cooked, remove the bacon from the grease with a fork or slotted spoon, and place it on a paper towel to cool.
Use a strainer to strain the solid bits from the leftover grease. Position the strainer over the bacon grease container and pour the grease into the strainer.
Put the jar of bacon grease into the fridge for short-term storage. For long-term storage, transfer the grease to a freezer safe container and put in the freezer.
Add a bit of bacon grease to the pan and carefully rub it in before drying it over the stove on medium heat. The best part is the flavorful fat adds a meaty, savory flavor to your pan for future cooking.
