Hazelnut cookies are the ideal delicacy for the chilly month of February, which calls for warm, soothing foods. They are a delicious winter delicacy because of their rich, nutty flavor, which goes well with chocolate, caramel, and spices. Whether it's buttery, crisp, or chewy, every version offers something unique. Serve them as a dessert or with coffee, or give them as a present to someone you care about.
