How far ahead can I blanch vegetables?
Undressed vegetables will retain their bright color and crisp texture for 1-2 days after blanching. If you put any kind of acid on them, such as vinegar or lemon juice, they will turn a sad gray color—the color they turn when overcooked.
The recipe for Green Bean, Chickpea, and Tomato Salad features blanched green beans that are cooked a day ahead.
