From myrecipes.com. Here's what the intro for this recipe says. In Peru, small streams wind their way from the mountains to the coast, and the delicious shrimp that fill them are cooked with local corn, squash, and potatoes to make this South American chowder called chupe. Don't peel the shrimp before cooking them in Step 1: The shells will flavor the cooking oil, which in turn will flavor the soup. The corn is traditionally left on the cob, but if the prospect of eating it this way (it is messy) bothers you, use two cups of kernels instead.
