No recipes, but as a kid we kept the bacon fat. When we had bacon, to make a sandwhich, we first lightly dipped the bread in the frying pan and then add the three strips of bacon. That was all we were allowed to have. Having bacon was a treat.
Another thing mom did. Take thin sliced steak like you'd use for a cheesestake, dip in egg and breadcrumbs. That one pound of meat now looks like three with all the breadcrumbs.....probably fried in bacon fat. After all the steak is used up, then mix up the breadcrumbs and eggs, fry that up too. This is why my brain goes crazy when I read threads of people throwing away leftovers the next day.
Now we save the bacon fat for the birds. Well mostly for the birds....hmmmm croutons
