- Heart. The heart of the radicchio should be firm and free of any signs of rot.
To best preserve radicchio for a few days, you can use the refrigerator: wrap it in a sheet of absorbent paper to absorb excess moisture and place it in the crisper drawer. Wash radicchio only before using it: water can encourage mold growth. Avoid plastic bags, which don't allow radicchio to breathe and can accelerate its deterioration. To preserve whole leaves longer, cut only the portion you need for your recipe.
How to Best Use It in The Kitchen
Radicchio, with its slightly bitter flavor and intense color, is an ingredient that can be used in countless recipes and pairs with a variety of dishes. Radicchio is excellent in salads, either raw, cut into thin strips and dressed with extra virgin olive oil, balsamic vinegar, salt, and pepper. It can be paired with other ingredients such as walnuts, gorgonzola, apples, or oranges to create flavor contrasts. It can be pan-fried, baked au gratin, or stewed, but it's also an ideal ingredient for filling savory pies, preparing risottos, stuffed pasta, or as a side dish. Sautéed in a pan with brown sugar and balsamic vinegar, it's perfect with cheeses or meats.
Radicchio can also be used with pasta, for example, paired with pork sausage to nicely balance the bitterness, or with gorgonzola, one of the most popular pairings. In addition to gorgonzola, radicchio also pairs well with other cheeses, such as Taleggio, Fontina, and Grana Padano.
