Home canning salsa is not an easy task. Out of 50 or so home canning salsa recipes that I have tried, only 3 or 4 actually tasted good enough for me to prefer it over either a fresh salsa, or a (God forbid) store bought salsa.
It's because of the need for acidity in the home canned salsa that they so often lack quality. Lemon juice or vinegar needs to be added in order to avoid botulism death, and that can seriously affect the flavor.
D-Wayne's wife Lori passed this recipe along and it is probably my favorite to date. It's simple and easy - but best of all it tastes effing awesome.
LORI'S SALSA
You need:
Approximately 50 normal sized tomatoes (obviously less if they're large, more if they're small).
3 Large Red Peppers
3 Large Green Peppers
2 Banana Peppers (or any sort of hot/sweet pepper)
3 Small Onions
4 Jalapenos (I add these, the original recipe does not call for them)
6 Cloves of Garlic (honestly...it's effing garlic - add as much as you want)
1/2 bunch of Cilantro
Blanch and de-seed your tomatoes first. Trust me, it may take a few extra minutes but it is well worth it.
Dice the tomatoes until you have approximately 2 quarts (save any leftover tomatoes, you'll need them later).
Chop all of the other veggies and place them in a large stock pot. Mix well.
Add 3 Tablespoons of Kosher or Canning salt to the top of the mixture - sprinkle it over the top but do not mix. Cover the pot with plastic wrap and a lid, and let it sit for at least 8 hours.
I leave mine sit on the counter, at room temperature for an entire day.
After allowing the mixture to rest, drain as much of the liquid off as possible, without removing the mixture from the pot. I simply poke a few holes in the plastic wrap and drain it into the sink.
Move the pot to a stove burner, and add:
3 Tablespoons Sugar
1/2 Cup White Vinegar
1/2 Cup Lemon Juice
1 Cup Water
and 1 Large Can Tomato Puree...WHAT??!! NO, NO, NO.
Why in the world would you spend the time to grow/purchase all of these fresh ingredients, chopping them by hand, with thoughts of popping a fresh jar in the middle of winter, only to use store bought effin tomato puree??!!
Make your own!
I use 1 quart jar of whole tomatoes that I canned earlier in the season, but any fresh tomatoes will do (see: left over from your chopping above). If you're using canned tomatoes you do not need to cook them, simply puree and add to your mixture. If you're using fresh tomatoes you're going to want to bring them to a boil, reduce heat and simmer for at least 20 minutes before adding to your salsa.
Once you have everything combined and mixed, bring the mixture to a rapid boil, then reduce heat to a slow boil and boil for at least 45 minutes - STIRRING VERY OFTEN. Allow mixture to boil until it reaches your desired consistency.
Adjust two piece caps, add to a hot water bath for 15 minutes, and effin enjoy.
