One thing I have done is julienned carrots or daikon radishes in a ferment. If you are sneaking in pickles. Spicy dill julienned carrots replace relish on hotdogs.
The ferment might go a bit faster. with the smaller cut.
My wife can't take spicy so I have to allow for that when adding peppercorns or chilies to the brine. Spicing up the brine is something that is a personal taste thing but garlic, caraway, chives find their way into some of my ferments.
Keeping the pickle under the brine with weights, an onion or citrus round, cabbage leaf helps if I don't have an airlock of some kind.
Cheesecloth and a jar was my first ferment vessel.
