Freezer Tomato Sauce:
Wash and core 20 large tomatoes; cut into
chunks. Place in a large kettle with 4 large onions,
chopped (4 cups); 4 large carrots, pared and shredded;
1/2 cup choped (fresh) parsley; 3 tablespooons sugar;
2 tablespoons salt and 3/4 teaspoon pepper. Bring
slowly to boiling, stirring often; lower heat and simmer
30 minutes, or until mixture thickens. Cool slightly;
then measure, 3 cups at a time, into blender container;
cover and whirl at high speed until smooth, about 1
minute. Pour into freezer containers in serving-size
portions, leaving 1/2 inch headroom. Seal, label and
date. Makes 16 cups.

Using Tomato Sauce
When ready to use sauce, place the clock of frozen
sauce in amedium size heavy saucepan; cover and
bring to bubbling over the very low heat, stirring
occasionally. Taste and season as you wish. For a
mildly flavored sauce, add 1 teaspoon leaf basil,
oregano, or thyme to each 2 cups of sauce, increasing
the quantity as you wish. Serve over pasta, with meat
loaf or in casserole dishes.

I also like to stew peeled tomatoes, chunks of onions
and green peppers, cool down and freeze in quart zip
lock bags. I use these pkgs. in casseroles and chili
throughout the winter.
