We made a version of this at a family get-together and tried it again the other day. The cayenne is good but make sure to add it according to your taste. The original recipe calls for tamari to taste as well, but we didn't use it. (I think tamari is a particular kind of soy sauce).

I got this recipe from mom, who said she got it from Jane.  I have made a lot of batches of these.  I can almost taste how good pork roast marinated in juice from these pickles then baked in the oven tasted.
