An ingredient only gets a page once at least 6 recipes on the site genuinely build on it. That is the difference between a page that shows something — one product handled six ways, in six countries — and a page that repeats what a single recipe already says. The best supplied are tomato, rice, cheese and potato.

The selection is not made from the shopping list but from what each recipe says about itself: a dish in which onion is merely an aromatic does not count as an onion recipe. It is also why bread and pasta have no page here: they name the dish, not what goes into it.
