Artichokes

Peak Season: March to May

Perfect Pick: Deep green and heavyset with undamaged, tightly closed leaves. The leaves should squeak when pinched together. One that is starting to open is past its best days.

Handle with Care: Store in the fridge in a plastic bag for up to 5 days.

The Payoff: A higher total antioxidant capacity than any other common vegetable, according to USDA tests.
