What You Need to Know
The baking powder in the dough decomposes under heat, releasing CO₂ that leavens the batter. Simultaneously, the oil’s high temperature gelatinizes starches and denatures proteins, creating a firm crust while the interior remains soft. Proper temperature control prevents excessive oil absorption and ensures even browning.
