Peppermint Patties

In large bowl, mix sweetened condensed milk, peppermint extract and food color. With spoon, stir in 1 1/2 packages confectioners' sugar. On cutting board generously sprinkled with confectioners' sugar, gradually knead in enough additional sugar so that mixture forms a smooth firm ball that doesn't stick to hands or board. Pat mixture into 8" X 8" square. With knife, cut into 1 inch squares. Shape each piece into a ball and with fingers, flatted into a 2 inch patty. Top with pecan half. Repeat with remaining pieces. (Keep pieces covered with plastic wrap while preparing patties) Let patties dry at least 1 hour.
