Jam-Tart Cookies

For filling these crisp tart-shell cookies, choose jams that are full of chunky fruit, not oversweetened and artificially stiffened with added pectin. Good flavor bets are strawberry, raspberry, cherry, apricot, and pineapple preserves. Assorted fillings will turn a plateful of cookies into a colorful dessert; garnish it with a few green leaves for an especially fresh and festive look.
