Before you trash your autumn decor, consider eating it. We’re not talking about your scented pinecones or those plastic berries; leave the leaves and the cinnamon potpourri out of your diet. Instead, go for the winter squash. They might be covered in warts; they might be green; they might look dirty and misshapen — just the look for your porch or windowsill. But they look better in an oven, and taste even better on a plate — or on a skewer or in a soup or in a pie — and endlessly worse when left rotting on the curb.
