The obvious use for dandelions is freshly tossed in salads. Pick the delicate, long, yellow flower petals off and top off your salad. (Bacon bits anyone?) Interestingly, the roots can also be peeled, sliced, and boiled. Or try steaming it and coating it in butter like a parsnip. The greens are also tasty sautéed like spinach, added to soup, or tossed in a stir-fry.
We know dandelions for their flowers but as a food, the greens are best early in the season before the flower grows. The leaves get increasingly bitter over time.
