For maximum crunch, be aggressive when salting and squeezing cucumbers—most salt drains away with the liquid. Gochugaru can be replaced with Aleppo pepper or a paprika-cayenne blend, but the flavor will differ. Store leftovers in an airtight container in the fridge for up to 3 days; do not freeze. Stir before serving as dressing may settle. To make it milder, reduce gochugaru or set aside plain cucumber slices for kids. Add gochujang for extra heat or pair with proteins like bulgogi, tofu, or rice bowls.
