A lovely pale lime green color, the small head of baby broccoli romanesco, pronounced roh-mah-NEHS-kah or roh-mah-NEHS-koh, is tightly packed with yellowish-green florets that spiral into a cone or pyramid-like shape. Varying in flavor, sometimes its sweet taste is similar to common broccoli. Sometimes it's a bit peppery and sometimes it tastes like sweet dense cauliflower.
