Long strands

A strand is pasta reduced to a single variable: the cross section. Everything a long noodle does follows from the gauge and the geometry of that little circle or oval. Thin strands carry oil films and light emulsions. Thick strands stand up to guanciale fat and reduced tomato. Pierce the middle and you get bucatini, which delivers sauce through the center. Flatten it slightly and the strand lays a face against the sauce instead of a tangent line. The family is eaten by the twirl, so its sauces must survive the fork: films, emulsions, and smooth coats, never chunks. Chunks fall off a cylinder. That is not a rule of taste, it is friction.
