Match the role: if you need tender leaves with mild sweetness, start with savoy or napa; if you need structure, use thin-sliced green cabbage.
Convert using the table ratios (e.g., 1:1 for savoy/napa; use ¾:1 for kale/collards/mustard).
Pre-prep for softness: slice thin for green cabbage, remove thick ribs for collards, and tear/kindly massage kale.
Adjust cook time: start ~20–30% shorter than your hispi plan, then add 1–2 minutes only if needed.
Taste-finish: add a small pinch of salt and a splash of acid or sweetness at the end to mimic hispi’s clean, lightly sweet flavor.
