After eating the last pickle save the jar of pickle juice. Then when a broccoli stem becomes available cut the tough outer skin off, chop it up and toss it in the pickle juice. Works well. They reach a taste that’s very close what the pickles tasted like. After 2 or 3 cycles of that the pickle juice starts losing its strong punch. Adding vinegar and a sweetener can help at that point if you don’t have more pickle juice by then.
Otherwise broccoli stems are not too versatile. They’re not that great in veg. stock because they bring a bit of bitterness. So I only use like ½ a stem in a pot of broth (which is wholly from veg scraps).
My next experiment (untested): reusing juice from a jar of jalapẽnos to pickle broccoli stems.
6·4 months ago- have gotten so used to just chopping the stems up and throwing them in with the rest of the broccoli in whatever I’m cooking at the time that I never thought of other options
- pickling is probably the easiest option – and along the lines of Japanese tsukemono, there’s plenty of quick pickle options
- or really go all out and take on fermentation – chop or shred the stems, add salt and aim for broccoli kraut or broccoli kimchi
