What You Need to Know
The dry heat initiates Maillard reactions between reducing sugars and amino acids in the rice flour, producing melanoidins and heterocyclic compounds like 2-acetyl-1-pyrroline (popcorn aroma). Simultaneous starch gelatinization at the surface creates a glassy matrix that traps smoky volatiles.
Transforms bland mochi into a snack with crisp caramelized crust, chewy interior, and umami depth that complements both sweet and savory toppings.
