Rhubarb

Once a home-baking staple, this sweet-tart vegetable (it's the leaf stalk of the plant, not botanically a fruit) has waned in popularity, and that's a shame. Rhubarb peaks in availability from April to June, grows all over the country, and can be used in savory applications like the tangy chutney below in addition to traditional sweet desserts.
