Place cherries and liqueur in a medium bowl. Cover and let stand overnight. Drain well, reserving the liqueur for another use, if you like. Place cherries on paper towels and let stand at least 1 hour until dry. Melt chocolate in a small, heavy saucepan, stirring frequently over very low heat (or melt in microwave oven at low power setting). Remove from heat. Place waxed paper on a baking sheet. Holding cherries by the stem, dip each into the chocolate to cover. Place on the waxed paper. Let stand in a cool, dry place, or chill until chocolate is firm. Makes about 28 cherries.
