Warm Spinach Salad with Shiitakes, Corn, and Bacon

I never liked raw spinach that much until I started eating it from my sister’s huge garden in southern Maine, where she and her husband grow almost everything they eat—a year-round endeavor, thanks to lots of canning, freezing, and the smart use of greenhouses and the like. She even brought me spinach seeds so I could start growing it in my own community garden. My garden is a tiny fraction of the size of hers, but the spinach comes out of it just as tender and sweet. This recipe barely wilts the spinach, so it still has that fresh flavor, but helps compensate for the sturdier texture of supermarket spinach, if that’s what you need to use, by softening it slightly. If you have tender garden-fresh spinach, you can feel free to let the topping cool before adding it to the spinach for a cold salad instead.
