For A.

Spaghetti Sauce for freezer

1/4 c olive oil
1.5 large onions, diced
6 cloves garlic, minced
12 c tomato, chopped
1 small can tomato paste
3T or more shredded carrot (depending on how sweet you like it)
1 t dried oregano, or more if fresh
2 t dried or 2 T fresh basil (or more to taste)
4 t salt (or to taste)
1 t black pepper

Saute onion about 3 minutes in oil over medium heat, do not let it brown. Add garlic and saute until onion is soft. Add everything else and cook at least 3 hours, partially covered. Blend in batches until desired consistency, then cook some more, until you are happy with it.

That's about as specific as I can get! I haven't made it the same twice, but it's certainly more crowd friendly when it's blended pretty smooth. A purist would seed the tomatoes. I think that's a waste of time.
