This classic corn and crab chowder will warm you through and through, even on the bitterest of winter days. The sweetness of the corn and crab combined with the saltiness of the bacon or salt pork create something truly magical. Additionally, the red-skinned potatoes bring a great element of color. It's not always easy to get fresh corn year-round, and frozen corn is perfectly fine. The starch from fresh corn, though, will have slightly better thickening properties than frozen. But most importantly, one thing you can't do with frozen corn that you can do with fresh corn is to grill it. The way the kernels get so beautifully charred and caramelized adds all kinds of complex flavors. Just grill the corn, let it cool, then slice the kernels off the cob and add to the soup as described below.
