This is my recipe for canned salsa. I make fresh salsa as along as I have tomatoes and peppers growing in the garden. But, when winter comes I need salsa in my pantry.
Ready 6 pint jars for canning. You can also get pint size freezer containers instead.
You will also need a water bath canner for canning.

20 medium size tomatoes- or enough to get 14 cups, chopped
3-1/3 cups seeded and chopped peppers – a mix of jalapeno and bell or Anaheim
2 cups coarsely chopped onions
1/2 cup chopped fresh cilantro or parsley- you can also use 1/4 cup dried
1/2 cup vinegar
5 cloves garlic, chopped finely
1 Tablespoon sugar
1 teaspoon salt
1 teaspoon pepper

Peel and seed the tomatoes. Chop and place in a colander to drain for 30 minutes to an hour.
Place the tomatoes in a dutch oven, probably about 5 quart size.
Bring to a boil and reduce heat.
Simmer, uncovered about an hour til thick and chunky. Stir frequently.
The juicier the tomatoes, the longer it will take to thicken up.
While, the tomatoes are cooking down, chop the onions, peppers, cilantro, and garlic.
Put that into a large bowl and add the vinegar, sugar, salt, and pepper.
When the tomatoes are ready add the pepper mixture.
Return mixture to boiling.
Remove from heat and ladle into the prepared jars.
Process in the water bath canner for 35 minutes.
If you prefer, ladle the salsa into freezer containers and freeze for up to a year.

You will get 5 or 6 pints.

If you want mild, use 3 cups bell or Anaheim and 1/3 cup jalapeno.
If you want medium, use half one kind and half the other.
If you want hot, use 3 cups jalapeno and 1/3 cup Anaheim.
Serranos are also good in this salsa.
