Feeling bitter about the holidays, or just overindulged with sweets? Chicories are your friends. These winter greens include radicchio, endive and puntarelle, and they add a slight bitterness to your life. Finely julienne endive for a chopped salad with citrus, pistachios and gorgonzola dolce. Or tear radicchio leaves and toss them with hot pasta, olive oil and garlic. You can also grill whole radicchio for a smoky addition to platters and salads. To be clear: Coffee with chicory does not include the leaves; it’s made with the roasted roots.
