Description
Precise thermal control converts rice starch into an elastic gel matrix.
Technical
Amylopectin in rice flour undergoes hydration and molecular reorganization at 60-75°C, forming a continuous network that traps water molecules. The addition of sugar (in gochujang sauce) elevates gelatinization temperature while promoting chewiness through hydrogen bonding interference.
Culinary Significance
Creates the signature bouncy-yet-tender texture of rice cakes that withstands spicy sauce without becoming mushy.
