Corn and beans have long been related — in history, in the garden, and in the kitchen. As two of the “three sisters,” as Native Americans call them, they coexist happily. Vining beans climb cornstalks, while big leaves of squash carpet the ground below. Modern gardeners tend to give each one its own bed, and most plant sweet corn instead of the flint and flour corns traditionally used in three sisters growing strategies. However, varieties of corn and beans have long been intertwined. It’s a treat to have them together in the summertime, such as in these sweet corn and shell bean recipes.
