Gherkins are not just a burger side. They are a flavour tool. Sweet and sour gherkins add crunch, salt and clean acidity, which means they work anywhere food feels a bit heavy.
Chop gherkins into tuna mayo, egg mayo or chicken salad for instant lift. Slice them into deli sandwiches with ham and cheese. Add them to potato salad to stop it tasting one note. Serve them on a cheese board to cut through rich cheddar and cured meats.
If you like snacking, gherkins straight from the jar are a very acceptable habit.
