Every single person in my family asked me today: what smells so good in the kitchen? And I'm sure the cats were thinking it too, even if they kept it to themselves.
What they smelled was me cleaning out the fridge. I had a giant (optimistically, a two-day) pot of soup on the stovetop, with everything in it that needed using up. And then I found one lonely slice of bacon, and made bacon cornbread to go with it.
I fried my little slice in the pan, then took it out to wait. Made up my cornbread batter and poured it in right on top of the bacon grease. Then cut up my bacon and sprinkled it around before baking. Just enough extra fat and salt to make it a good cornbread upgrade.
