These puff pastry-wrapped olives are our family's favorite holiday appetizer. We make them with a variety of olives - pimento stuffed green, plump kalamata, Provencal - just make sure they are pitted. We like to use strongly flavored olives; the flavor of canned ripe olives disappears in the puff pastry. You can make these ahead, and freeze; allow 30 minutes for the pastry to thaw before baking. Another advantage: the kids like to make them and eat them.
