Description
Continuous stirring prevents starch gelatinization from forming lumps in masa-thickened chocolate beverages.
Technical
Mechanical shear forces from stirring disrupt hydrogen bonding between amylose molecules in corn masa, preventing localized gelatinization that leads to clumping. The constant motion ensures even heat distribution for uniform starch swelling.
Culinary Significance
Essential for achieving the smooth, velvety texture characteristic of traditional champurrado, a thick Mexican chocolate drink.
