Mochi Dough: Why Pre-Cooking Matters

Mochi is made from glutinous rice flour, also sold as sweet rice flour or mochiko, which has a high amylopectin starch content. That starch must be fully gelatinised by heat and moisture to give mochi its characteristic chewy, stretchy texture. If the dough is fried raw without pre-steaming or microwaving, the starch remains uncooked and the result is dense, gummy, and hard to eat. In the challenge, time pressure forced the mochi team to skip the pre-cook step before frying, which was exactly the problem judges identified. At home, always cook the dough through before shaping, filling, or frying.
