I tried this once before, many years ago for my Mother who adores Pickled Green Beans.
We use to be able to buy it in the Supermarket, but for some reason, they stopped producing it I guess. I do see from time to time in specialty stores, the stuff in jars, but egads! The are pricey!
I mish-mashed the Ball Recipe with another to create my own version.
Garlic Cloves, Mustard Seeds, fresh Dill Frowns and Seeds too, to equal parts White Vinegar to Water along with the appropriate amount of Canning/Pickling Salt.
I purchased fresh Green Beans at the local Green Grocer for a fairly inexpensive cost and I wound up with 4 1/2 pints & 2 pint sized jars.
That's a bit too much for my Mom, I know, so I shared the 2 pint jars with neighbors. The one neighbor said that she hadn't had Dilly Beans since she left Maine, something like 10 years ago.
