Find your favorite BIG jar with a lid. Make sure it's squeaky clean! Peel and slice enough cucumbers, red peppers and sweet onions to fill the jar to the brim. Can add Jalapenos if desired, too. (They shrink when the hot brine hits them.) 2 cups water, 2 cups white vinegar, 2 cups sugar. Boil those together until the sugar is dissolved, stir a few times. (Should just be bubbling; doesn't have to be a rolling boil.) Add 2 Tbsp chopped garlic to the brine, then pour it into the jar. Let the mixture cool, then cap and put in the fridge. Tasty the very next morning. Keep stored in the fridge, and I tip the jar over or shake it up when I think of it. Totally yummy.
Southerners have done something similar for a very long time, but often put a little sugar in to counterbalance the tart and salty. Done in this manner, it can function almost like a chutney with seafood or cooked vegetables. Its eaten solo as a salad in hot weather.
No dill?
