Identify your use-case: raw/crunchy topping, kimchi-style salting, stir-fry/soup, or quick pickling.
Choose the closest texture first (firm daikon/luobo for crisp; turnip/celeriac for cooked dishes; jicama for raw crunch).
Swap using the table’s 1:1 ratio, then match cut size (thicker cuts stay crisper).
If the substitute is wetter (often jicama/celeriac), pat dry or salt briefly and drain before cooking.
Taste and adjust seasoning: radish substitutes can read blander or more peppery—add salt/acid to balance.
