Cookie Cutters

Plastic ones may seem more practical (and safer, if you're baking with children). But copper or tin shapes are sharper and more effective, especially if you're making a large quantity. Plastic cutters can also warp if stored improperly (e.g., in a cabinet above the stove, where they're susceptible to high heat). For very large cookies where even slightly distorted shapes will be obvious, splurge on copper; it's sturdy and won't bend.
