Pickling is a method for preserving vegetables by canning. Only acidic fruits and vegetables (e.g., tomatoes) can be safely canned with the boiling-water bath method. Other non-acidic fruits and vegetables need to be acidified for safe home-canning (plus, frozen vegetables just taste better).
(1) Wash vegetables and cut to size so they fit into your sterilized jars with some room to spare at the top (it's important that all parts of the vegetable come into contact with the pickling solution). Seed cucumbers if you prefer.
(2) Bring to boil equal portions water and vinegar with 1/4 cup salt for every 5 cups of liquid.
(3) Pack sterilized jars with a garlic clove, 1/2 jalapeno, a few coriander seeds, a few peppercorns, a hefty pinch of mustard seeds and dill flowers. Pack in vegetables.
(4) Pour boiling pickling solution into jars, leaving about 1/2 inch of space at the top. Be sure all vegetables are covered with the solution. Seal tightly.
(5) Process in boiling water bath for at least 10 minutes (we processed the cucumber pickles for 20 minutes, as suggested by The Joy of Cooking).
(6) Leave jars to pickle for at least 1 week before opening. Store at room temperature.
