Sentence:  This beautiful vegetable looks rather like a green cauliflower designed by a mathematician and has lime-green 'spiralled' curds. The curds are nutty and tasty, and <WSD>romanesco</WSD> is worth growing just for its good looks. You can use <WSD>romanesco</WSD> in the same ways that you would normally use cauliflower but the flavour is sweeter and they look far more impressive. I try to leave them in large pieces when serving them because they're so beautiful. 
Meaning of the word marked with <WSD> tags:  (Romanesco broccoli), a light-green edible flower bud of the species "Brassica oleracea", which is thus related to broccoli and cauliflower. Its form is a natural approximation of a fractal.
