Also brined some peppers. HATE the smell.
Is it the vinegar-y odor or just the odor of the spices that you dislike?
Not sure but it has a foul odor. Don't think it's the spices. Maybe too much onion?
What recipe are you using? If you are pickling jalapenos, I'm not sure why you are "boiling down" the brine and why you are using double the amount of water to vinegar. Most recipes has a 1:1 ratio of vinegar to water and the brine is brought to a boil and only simmered for 5-10 minutes or until the sugar & salt dissolves.
