Preheat oven to 400ºF.

Trim bottoms of stems and any wilted leaves off Brussels sprouts and halve each one.

Put fat in a roasting pan, and if you’re using bacon grease or lard, put it in the oven for a few minutes to melt.

Add Brussels sprouts to the pan and toss till they’re coated with fat. Salt and pepper and stir again, then put them in oven.

Roast for 35 to 40 minutes, stirring now and then. When they’re evenly browned, they’re done. Add a little more salt if they need it and serve.
