Romanesco Broccoli

Romanesco Broccoli

If you’re a fan of fractals, Op Art, or vegetables that look like they’re from outer space, Romanesco broccoli is for you! This 16th century Italian heading variety looks too pretty to eat, but if you do, you’ll be rewarded with a mild, slightly nutty, and somewhat sweeter flavor than most broccoli varieties. The chartreuse color and fractal spirals make a stunning display in your garden and on your dinner table. Romanesco broccoli can be steamed but is especially delicious roasted. Cut into florets or cook and serve whole—leaves and all.
