What's a standard pickling recipe for every liter?

Can anyone put both quick pickle and 1 day pickling?

Maybe also include if anyone has a fridge pickle recipe

I'm learning to pickle just now

what's a pickle you make for one specific dish, rather than just snacking straight from the jar?

especially curious about combos for chili, rice bowls, or sandwiches. tell me the vegetable + the dish + what makes it work. red onions get all the publicity, give the supporting cast a chance lol.
