Why is radicchio so bitter?
Likewise, how do you eat radicchio?
Radicchio is great as a leafy salad vegetable, and it adds a sharp, pungent flavor. Eat it raw in salads, or lightly grill or sauté it to add to salads, pasta dished, stews or risotto. To prepare, trim the outer leaves, wash the head in cool running water.
Likewise, how do you make salad less bitter?
Sautéing greens in oil with lots of garlic and/or onions works well to counteract the bitterness of mildly bitter greens. Counterbalancing with acid, salt and strong flavors. A bitter salad green like arugula (rocket, rucola) demands a rather strong tasting dressing.
Just trim and cut the endive, toss with olive oil, a pinch of sugar, salt and pepper, then roast at 400 degrees until tender. Drizzle a little sherry vinegar all over, then serve either hot or at room temperature. It makes for a great side dish or buffet offering.
