Vinegar, salt and a little sugar and water. Its a simple brine with no spices added. Easy to make, and you simply taste it to see if its got enough taste. The water amount would be less than 1/4 the total, or none at all liquid. White distilled vinegar is used. I make this with a bit of Splenda, as they are sweet peppers. I also pierce each pepper with a skewer through them to allow penetration of the brine.
