What You Need to Know
Boiling at ~100 °C for 3–5 minutes causes starch granules in the dough to swell and gelatinize while gluten proteins unfold, creating a firm yet tender matrix. Salt and optional acid (vinegar) adjust the gluten network's strength, preventing rupture, and a brief simmer (90–95 °C) can protect delicate fillings.
