Chocolate Kahlua Truffle Cookies

2 1/2 cups finely crushed chocolate cookie crumbs
1 cup finely chopped nuts (your choice)
1 cup sifted powdered sugar
1/3 cup coffee liqueur
1 tbl water -- (1 to 2)
5 ounces semisweet chocolate, chopped
1 tablespoon shortening
6 ounces white baking bar, chopped

In a large mixing bowl stir together the chocolate wafer crumbs, chopped nuts, powdered sugar, and Kahlua or other liqueur. Add enough of the water so crumbs hold together.

Shape mixture into 1-inch balls. Place on a waxed paper-lined cookie sheet.

In a small, heavy saucepan heat semisweet chocolate and shortening over low heat till melted.

In another small, heavy saucepan heat white baking bar till melted. With a fork, dip half of the cookies into the semisweet chocolate mixture to coat; place on cookie sheet.

Dip remaining cookies in melted white baking bar to coat; place on cookie sheet. With the tip of a spoon, thinly drizzle white baking bar mixture in a zigzag pattern over cookies coated with semisweet chocolate.

Repeat with semisweet chocolate, drizzling over cookies coated with white baking bar mixture. Refrigerate for about 30 minutes, or till chocolate is firm. Store in refrigerator.
