Onion
Yellow or red, raw thin or cooked low; the sfincione anchor.
About
Onion plays two pizza roles. Raw, thinly sliced red or yellow onion goes on right before the bake for a sharp counterpoint to cheese (NY-style, grandma). Slow-cooked, sweet, jammy onion goes under the cheese on a sfincione or a white pie, contributing sweetness and depth. For sfincione, sweat 2 large yellow onions in olive oil for 30+ minutes over low heat until pale gold and silky.
