If you are ever searching for a new pickle recipe that might suit you. You should look at
How to Pickle
They also have an excellent guide they sell there.
I think it may depend somewhat also on what other foods you are serving. If you are serving some dryer meets such as turkey or maybe pot roast, I dunno, you may want to provide a 1/2 cup of gravy per person for those wanting to use it on their meat.
