Here's a spaghetti sauce recipe that I've been making for more than 20 years. It's from a food column by John Owen called 'The Intermediate Eater'.
1 lb ground round
3/4 lb ground Italian sausage
2 med onions,chopped
1 green pepper,chopped
2 stalks celery, chopped
4 cloves garlic,minced
6 sprigs parsley,chopped
1/2 cup (loose) porcini mushrooms (soak in a cup of warm water until soft)
1 can (4 oz) mushroom pieces and stems
(use 8 oz mushrooms if porcini mushrooms not used)
2 tbs olive oil
1 can (6 oz) tomato paste
1 can ( 16 oz) tomatoes, finely chopped
38 oz tomato sauce
1 can (8 oz) tomato juice
1 cube butter
1 cup water
1 tsp beef bouillon base
1 tsp basil leaf, crumbled
1 heaping tsp rosemary, crumbled
1 tsp sage, crumbled
1 1/2 tbs Kitchen Bouquet
1 heaping tbs sugar
1 heaping tbs salt (if desired)
1 1/2 tsp pepper
Saute the ground round, parsley and garlic. Drain and add to the pot. Fry the sausage as you did the ground round, drain and add to the pot. In the same skillet, heat the olive oil and saute the ground green pepper, onions and celery for about 5 minutes. Add that to the pot, too, along with the chopped mushrooms.
Add all the remaining ingredients and simmer for an hour or two. If you want to be sure the sauce is the thickness you prefer, you might add the cup of water listed above in slurps as needed.
