I have thought about this. The recipe for dilly beans is a tested recipe through most of the university extensions, the vinegar to water ratio is almost one to one, while pickles are a little less vinegar to water, 3/4 to one. The dill pickle chips I want to make will probably use the least required vinegar for a tested recipe and heavy on the salt--it's just for hamburgers--at least in this house.
I read the University of Minnesota pickle bill and they had interesting SAFE information regarding different PH's required for different foods.
Here:
Pickle Bill Fact Sheet
Examples of pH for different foods (for selling home canned foods)
dill pickles (pH 2.6-3.8), tomatoes (pH 3.7-4.9), distilled water (pH 7), garlic (pH 5.3-6.3).
Beans cannot, say, be sold when canned from the kitchen because they are considered low acid food and it makes sense that the pickling solution for them is stronger than for cucumbers.
Good suggestions--now I've stretched my cucumber pickling brain as far as I ever hope to go.
