What You Need to Know
The rapid heat transfer during frying initiates the Maillard reaction between amino acids from fava beans and reducing sugars, producing melanoidins that give the characteristic brown color and nutty flavor. Simultaneously, moisture evaporates, creating a vapor pressure that drives oil into the batter, while a brief flash at >190 °C forms a surface barrier that limits further oil uptake. Precise temperature control is essential to balance browning, texture, and acrylamide formation.
