How the base becomes white

Growers draw soil up around the lower part of the plant to exclude light and extend the white portion. This earthing-up method explains the color difference between the sheltered base and the exposed green leaves.

Try it in the kitchen

Cook sliced mature leek in a potato soup, or grill young leeks and dress them with olive oil. Baby leeks are tender; plants left to grow longer reach a larger size.

Leek is among the vegetables traditionally served with bagna cauda in Piemonte. It offers another way to bring this vegetable to the table alongside the shared sauce.

Choose the size for the dish

Choose young, smaller leeks when you want to present them whole, or larger plants when you plan to slice the base. The stage of growth is a useful distinction alongside any cultivar name.
