Bacon grease really isn't all that good a substance to fry stuff in.
I usually put a little canola oil in the bottom of my pan before frying. I like it because it has a really high smoke point, unlike olive oil which smokes like crazy if I put the heat on anywhere past medium. Turns out, bacon grease does the exact same thing. Jesus, it looked like a god damn hot box in my kitchen when I was done cooking breakfast. I even took the battery out of my smoke detector, 'cause it was bound to go off like a fuckin' air raid siren.
So, in conclusion, while it sounds like a great idea to fry things in bacon grease... it's really just more trouble than it's worth.
