Was in the "area" of a funky (GOOD) supermarket the other day, so stopped in. It's little, jam packed, aisles so narrow it takes serious maneuvering for 2 carts. In small produce section... the basics of carrots, onions, poatoes, peppers, etc... they had 2 lb bags of string beans for $1!?! They looked great but 2 lb is a LOT of beans... especially for one person. Decided to try my hand at green bean pickles... googled a recipe. Simple brine of cider vinegar, sugar, spices and garlic. Said to bundle pickling spices, pepper corns, bay leaves in cheese cloth and simmer for something like 10 minutes. Couldn't locate cheese cloth that I KNOW I have (somewhere), so used one of my tea balls for containment. I used microwave to heat up vinegar and sugar till about boiling and just let tea ball steep... knew I couldn't heat it cuz tea ball is metal. Beans were blanched for about a minute and packed into jars with thin sliced onions and red peppers. As I was cutting things up and packing into jars, realized I had forgotten the garlic... supposed to be steeped in brine, too. So fished out tea ball, reheated brine, and added 3-4 well-smashed cloves. By the time I was ready to pour brine in jars, the relativelt intact cloves were BRIGHT GREEN?? Any idea why that happened?
