I was trying to create an appetizer that could be served at my teenaged daughters birthday party that the kids would love but that would appear elegant enough for the adults to be interested as well. These are made with simple ingredients yet yield a sophisticated result. Feel free to get creative with the flavors. Try shredded white cheddar in place of mozzarella or thyme instead of the rosemary. Take it up another notch by topping the rounds with smoked fish. Amanda Digges, South Windsor, Connecticut.
