Biang Biang noodles are a type of hand-pulled noodles get their name from when they are pulled/stretched and slapped on the table. They are chewy, springy, wide noodles that get their incredible texture from gluten. Gluten is composed of two proteins called glutenin and gliadin, when the proteins are mixed with water they form disulfide bonds and crosslink. This forms a stretchy and thick structure with high elasticity. This is a conceptual animation of how this protein structure imparts elasticity.
One of Vessel Studios’ go-to places to order hand pulled noodles is Xi’an Famous Foods. Xi’an Famous Foods is based in New York and serves food inspired by food from Xi’an, China. Xi’an Famous Foods ships meal kits https://xiankits.com/ that include the dough and ingredients to make the noodles at home. My favorite kit is their Spicy Cumin Lamb Hand-Ripped Noodles kit.
