First, I mix the meatloaf ingredients: 1 lb ground beef, a good squirt (1/8 cup or so) of ketchup, herbs and ground pepper (I use plenty of sage and rosemary, sometimes thyme), and about 1/4 cup potato flakes.
On the side, I mix together a good squirt of ketchup (1/8 cup or so), and at least a teaspoon each of cloves, nutmeg, and cinnamon. I do a little extra cinnamon.
