Rinse off any dirt from cucumbers and scrape off the flower end of the cucumbers to ensure there are no flowering parts (enzymes & molds can make pickles mushy). If using slicing cukes, slice into ¾″ thick pieces. Leave whole if using pickling (Kirby) variety.
To a clean quart glass jar or ceramic crock, add fruit tree leaves, cayenne and California chile powder.
Cut stem off pepper, then slice in half lengthwise. For more heat, leave seeds and membranes intact. For less chile heat, scrape seeds and membrane out, leaving only the fleshy part. Add to jar.
Add cucumbers to jar.
Mix Brine: Stir sea salt into filtered water until salt dissolves.
If using, add pickle brine from a previous batch to container.
Place a lid or plate that is slightly smaller than the diameter of the container on top of cukes. Add a weight like a jar or wine bottle filled with water. OR, If using a small batch fermentation kit, add the weight(s) to the jar.
Slowly pour brine into jar until there’s enough to cover the contents. Leave about one inch from the top of the container (if using mason jars).
Cover container with a tea towel or clean dishcloth to keep dust and flies out, and secure with twist ties or a rubber band. OR if using small batch fermentation kit, apply the fermentation lid per the instructions.
