Description
Flash-frying technique using a delicate starch batter chilled with ice water to create ultra-crisp, lacy textures.
Technical
The batter's viscosity is controlled by potato starch's high amylopectin content (80%) and ice-cold water's suppression of gluten formation. Rapid vaporization at 180°C creates microporous structures via starch gelatinization and protein denaturation.
Culinary Significance
Creates ethereally crisp coatings that stay crunchy longer than wheat-flour batters, ideal for delicate ingredients like tofu or seafood.
