A leafy cruciferous vegetable cultivated for its pungent bitter leaves, tender stems, and small unopened flower buds, prized throughout Italian and Asian kitchens for its assertive flavor and quick-cooking versatility.
History & Origins
Broccoli rabe, known in Italy as "cima di rapa" or "friarielli," has been cultivated in the Mediterranean for over two millennia, with references in Roman-era agricultural texts and continued strongholds in the southern Italian regions of Puglia, Campania, and Sicily. Italian immigrants carried the plant to the United States during the late 19th and early 20th centuries, where it became a fixture in Italian-American neighborhoods of the Northeast. Today it remains an emblem of Apulian cuisine and is grown commercially in California, New Jersey, and increasingly in China.
