Can one possibly get more yellow than that? Wait, the butter is yellow too, and turmeric stains everything it touches yellow. This recipe uses a couple summer seasonal ingredients—the corn and squash—but you could easily substitute a sweet potato (put it in early with the Yukon Golds). My mother and I both loved it, especially with some cilantro mixed in. My father doesn’t like curry so his vote doesn’t count. Garnish with chopped cilantro (or parsley, though cilantro is particularly good with this soup).
