I have used alum (aluminum potassium sulfate) before, but don't really like
eating more aluminum than the minimum.

I've made pickles for years with pickling lime. A few years ago I
switched to calcium chloride and have a good results with that and the
same snap throughout the pickle. Calcium chloride is easier to work with
than pickling lime in my opinion.
Here's where I got my last shipment of calcium chloride:

When y'all go to use the lime, be sure to rinse it out well as the
directions say. Taste'em, then rinse again. That wierd bitterness will not
get better as they age, to my regret.

Pickle Crisp, calcium chloride, the only way to go instead of pickling
lime.
