1. Spray a 9" X 9" pan with non-stick cooking spray and line with parchment paper.

 

2. Combine gelatin with 1/2 cup cold water in a small bowl and set aside for a few minutes to soften the gelatin.

 

3. Combine the sugar and 3/4 cup water in a saucepan and bring to a boil over medium high heat. Remove from heat and add flavoring, Tart & Sour (if using), and food coloring. Add the gelatin mixture to the hot syrup and stir with a wire whisk until gelatin is completely dissolved. Stir in more food coloring if necessary to attain desired hue.

 

4. Pour into prepared pan. Refrigerate several hours until well chilled or overnight.

 

5. Coat a large cutting board with sugar and turnout the chilled block of gelatin onto the board. Use small cookie cutters to cut out shapes or use a knife to slice the block into large strips, then slice each strip into squares. Toss gumdrops in a bowl filled with sugar. Transfer to a colander to shake off excess sugar. Place individual gumdrops on a sheet of waxed paper and allow to air-dry for a day or two to crystallize.

 

6. Store in an airtight container.
