I know we’re supposed to get all worked up that Chelsea Clinton spent money on a wedding when she could have fed Haiti for all time for the cost of her dress. The only thing that got to me was that the cake was gluten-free. I realize there are people who have real celiac disease. But it’s rare, maybe 1 percent of the population. Aside from lactose-level marketing, there’s no reason stuff like mayonnaise has to be labeled gluten-free. (Check your Nivea, though.) And who would think wedding cakes are meant to be eaten?
