Preheat oven to 325 degrees. Line cookie sheets with parchment paper. Break almond paste into small piece and place into food processor or mixer. Add sugar and mix well. Add the egg white and mix until moist and sticky (tacky); Approximately 2 minutes. Spoon almond mixture into large pastry bag fitted with a # 6-star tip. Pipe into stars about 1 1/2 inches in diameter or drop by rounded tablespoons on to lined cookie sheet about 1 inch apart. Top with 1/2 maraschino cherry. (optional) Bake 20 minutes on middle shelf, move to the upper shelf, (about 4" above the middle shelf); for approximately 8 minutes until light golden brown. Move parchment paper with cookies onto baking racks to cook. When completely cool carefully peel macaroons off the paper. Store in an airtight container
Notes
I use a silicone liner to line my baking sheet instead of the parchment paper. It is easier and much economical is you bake a lot. Recipe adapted from solofoods.com
