I make a lot of home-made pickles; mostly pickled onions/shallots/cucumbers. I use a cold process and I don't pre-brine.
I notice all of my pickles always end up floating to the top of the jars, even after months of pickling. This is very annoying because it means the top pickles don't get evenly saturated.
Commercial, store-bought pickles never have this problem. They always sink to the bottom of the jar. Even if there's only a single pickle left in the jar, it sinks.
What can I do to get my pickles to sink?
