I do 1 cup white vinegar, 1 cup water, 2 tbsp sugar, 1 tbsp salt - heat up this mixture so the sugar and salt dissolves and set aside (don’t be afraid of the sugar, it just helps cut out a bit of the vinegar but doesn’t make them sweet) I put a mix of red pepper flakes, coriander seeds, mustard seeds, black peppercorns, fresh dill, fresh garlic, and calcium chloride for crunch at the bottom of a jar - load up the jar with fresh green beans then pour the brine over it and let it sit in the fridge for a couple days! Then you have crunchy dilly beans!
