Though classified as (and also called) a summer cauliflower, this vegetable's appearance is so uniquely striking that it deserves its own listing. Like regular cauliflower, Romanesca has a tightly compact head of florets attached by clusters of stalks — but there the similarity in appearance ends. Romanesca, which hails from northern Italy, is a beautiful pale lime green color; its florets, rather than being rounded, rise in a pyramid of pointed, spiraling cones. Its flavor is somewhat more delicate than that of regular cauliflower. Romanesca is available only briefly — from September through November. Choose a firm head with crisp leaves. Store in a plastic bag in the refrigerator for up to 1 week. Romanesca can be cooked in any fashion suitable for regular cauliflower. It makes beautiful cruditéS, and is stunning cooked whole.
