Orange-Saffron Stamp Cookies
Saffron threads are the stamens of crocus flowers, and without a doubt, they're a splurge. (A tiny jar costs about $10.) There isn't a good substitute, so we reserve saffron for recipes like these soft, citrusy cookies, where its flavor and color shine.
Layer cookies between sheets of waxed paper in an airtight container: cover. Store at room temperature for up to 3 days or freeze up to 3 months.
