I have a hellva time trying to grow pickling cukes. They haven't turned out. I have bought them at the Farmer's Market and made bread & butter and dill pickles. Not too long ago I made Deli-Style pickles with air-lock quart jars via the ferment method. They were good. I need to add more spices, garlic, etc. next time. I pickled green beans, too! Got a jar in the fridge now. Your jars of pickles look really good!! Add 1 teaspoon mustard seed per qt, 4 fresh sprigs of dill per qt, 1 teaspoon of pickling spice per qt, 6 cloves of fresh garlic per qt, I slice of onion per qt. add superhot pod cut in half. This will add good flavor before the burn start.
