I save mine. You mean the grease that is left over after frying bacon, right?
It makes a good seasoning for vegetables. For example if you would put a little butter or olive oil in your green beans or corn, add bacon grease instead.
Stirfrying veggies
pan frying anything (pancakes, salmon patties, eggs) where you need a little grease in the pan to prevent sticking.
I have never tried it on bread. That doesn't sound great... but I wonder how it would be spread on hot cornbread. Hmm... I am intrigued. I may try it on hot baked potatoes instead of butter.
I have lately been using it to grease my waffle iron before using it. Until recently, I'd use cooking spray for that. But I've quit using the stuff--deciding it was a recent invention that is really an unnecessary expense.
To save mine, I put a wire strainer on top of my grease jar, put a coffee filter inside the strainer and strain the grease through the coffee filter. It makes for a really clear and creamy fat. (Yes it looks creamy!) Then you can use the greasy coffee filter for greasing up pans or waffle irons. Cover with a lid and store in the fridge.
What I would really like to know... (yelling) PAT!!!!!!!!!!! ... is at what temperature bacon grease starts to burn, and therefore if it could be used for deep frying--hush puppies or corn fritters, etc.
ETA: By clear, I din't mean transparent. I mean free of debris. LOL Also, use it for cooking dried beans. It has never occured to me that it's even possible to cook dry beans without adding a big dollop of bacon grease. But since no one else has mentioned it, I guess I was wrong.
