Using rubber gloves, cut stems from jalapenos, and cut them in half lengthwise.
Remove stems and cores from tomatoes and chop in a very large dice.
Peel onion and roughly chop.
Peel garlic – leave half of the cloves whole. Mince the other half finely and set aside.
Roughly chop the cilantro, leaves and stems.
Place all of the above [except the minced garlic] in a heavy bottomed 5 quart pot.
Juice the limes, and add the juice to the ingredients in pot.
Add the salt, pepper and water, and turn the heat to medium.
When the mixtures gets up to a boil, reduce heat so that it stays at a simmer, and
Cook for about 30 to 40 minutes, until the peppers and tomatoes are very soft.
Remove from heat, and use an immersion blender to liquefy the ingredients, to achieve a uniform, slightly chunky texture. This can be done in a food processor as well.
Place back on the heat, add the remaining minced garlic, and the vinegar. Bring back to a simmer and cook for 5 minutes. Makes about 6 pints.
Notes
This can be water bath canned to make it shelf stable. The amount of vinegar means it only needs to process for 10 minutes, once the canner is at a full boil. You can see the Blueberry Preserves post for more instructions on water bath canning, or consult the Ball Complete Book of Home Preserving for detailed guidance.
