So, here, as requested, is the way I make meatloaf.
1 pound of ground beef, I use ground sirloin
1/2 pound of ground pork
2 slightly beaten eggs
1/2 cup of crushed dry bread crumbs
1/2 cup of chopped onion
1/2 cup of chopped green pepper
1/2 cup of chopped celery
A couple of cloves of chopped garlic
1 teaspoon of white pepper
1 teaspoon of red pepper
1 teaspoon of black pepper
1 teaspoon of salt
1/2 teaspoon of cumin
1/2 teaspoon of thyme
Put 3 tablespoons of butter in a skillet and turn the heat high enough to make the butter melt and bubble. Dump in the vegetables and seasonings, keep stirring the whole thing with a wooden spoon and cook the vegetables until they're transparent, but don't burn the garlic.
Meanwhile mix the beef, pork, eggs and bread crumbs together in a big mixing bowl. Then pour in a little milk, just a little. When the vegetables are cooked pour the whole thing into the mixing bowl and mash it all together with your hands, mixing everything together. That part is rather gross. But what you're doing is making a gigantic meatball.
When you've got the big meatball just roll it into a baking pan, the one I like to use is Pyrex, form it into a loaf but keep the sides of the meatloaf sloping in away from the sides of the baking pan.
Put that in your 450 degree oven for around thirty minutes. Take the pan out and pour the drippings into another pan to use for making gravy. Let the meatloaf rest for, say, five minutes and there you go.
