I made this recipe and canned it today. I pretty much followed the recipe except that I put in 1/4 cup chopped cilantro (and left out a little bit of the onion and jalapeno, about 1/4 worth). Instead of cayenne pepper, I put in a finely chopped cayenne pepper since I had so many from my garden. My tomatoes were not Roma and were pretty juicy. Result: Very Hot!!! (so maybe a whole cayenne pepper was too much??), and only made 3 1/2 pints (I realize results can vary, and my tomatoes probably cooked down quite a lot). All in all, very tasty! PS: Thanks for reminding people to wear rubber gloves when handling hot peppers! I will probably try this again with the other variety of tomatoes that I grew this summer, Russian Black (the ones I use today are called Stupice).
To start with, mix the corn, olives, red bell peppers, and onions into a large bowl. In a smaller bowl, put together garlic, olive oil, lemon juice, cider vinegar, oregano, salt, and pepper. The corn mixture can then be added to this secondary mixture before they are thoroughly combined together. At this point, the dish needs to sit overnight in a refrigerator. The avocados should be added into to the mix right before the dish is served.
