Before any other sumptuous spring fruits start to find their way into gardens and onto our plates this spring, don’t forget to give rhubarb some well-earned attention. Rhubarb is a hearty and undemanding perennial vegetable known for adding its sour, pucker-inducing flavor to our beloved springtime and early summer recipes. Although the time-honored strawberry rhubarb combo is sure to please, don’t hesitate to use those voluptuous rhubarb patches in baked goods before strawberry patches are productive enough to fill farm stands. This rhubarb olive cake recipe has all the makings to become a springtime baking staple. The cornmeal adds texture to the lightly sweetened cake, studded with chunks of rhubarb that surprise while satisfying. The 40-45 minutes of cooking time allows plenty of opportunity to encourage everybody to try a chunk of raw rhubarb too, one of the garden’s most surprising and awe-inspiring flavors. Be sure to have the camera ready for the pucker!
