1 gallon glass jar or ceramic crock
1/2 a gallon of warm water (tap water is fine)
A handful of fresh, clean grape leaves, oak leaves, or cherry leaves (optional — they supply tannins to keep the pickles crunchy) (UPDATE: raspberry & blackberry leaves work too, but have a stronger flavor than grape leaves)
3-4 lbs of cucumbers (small to medium is ideal, but if all you have is large, cut them into spears)
5-6 Tbsp non-iodized sea salt. I use Redmond RealSalt brand unrefined sea salt. (I usually prefer 6 Tbsp. Using 5 Tbsp of salt will yield a less salty pickle that my hubby prefers, however you may have to contend with more white film, or “kahm yeast,” on the surface of the brine during fermentation. More about kahm yeast in the instructions.)

2 – 3 heads of garlic, separated into cloves, peeled, & roughly chopped
3 Tbsp whole dill seed
2 Tbsp whole coriander seed
1 tsp whole mustard seed (brown or yellow, doesn’t matter)
1 tsp whole peppercorns
1 tsp fennel seed
1/2 tsp red pepper flakes
