Flavor profile

Radicchio's bitter compounds (primarily lactucopicrin and related sesquiterpene lactones) are water-soluble — soaking shredded radicchio in cold water for 20–30 minutes reduces the bitterness significantly for raw applications. Heat treatment (grilling, roasting, sautéing) also reduces the bitter compounds and caramelizes the natural sugars, transforming radicchio into something sweeter, more complex, and less aggressively bitter than raw. Quartered or halved heads of Treviso grilled until charred and wilted are extraordinary with olive oil and sea salt. In pasta (with pancetta, Gorgonzola, and walnuts), radicchio's bitterness is countered by the fat and salt of the cheese. The classic Venetian risotto di radicchio uses Treviso radicchio braised with red wine into a rich, slightly bitter risotto. Raw radicchio in salads works best with bitter-complementing elements: sweet (orange segments, honey-based dressing), fat (walnuts, burrata), or salt (anchovy, prosciutto, parmesan).
