Description
Precision alignment of gluten networks through controlled mechanical stress.
Technical
Hydrated wheat proteins (gliadin and glutenin) form disulfide bridges during shearing. Laminar flow aligns polymers parallel to rolling direction. Starch granules become compressed between protein layers.
Culinary Significance
Creates uniform texture for even cooking. Thinner sheets yield delicate textures (like angel hair), while thicker sheets provide chew (like pappardelle). Hand-rolled versions retain micro-textures that hold sauces differently.
