  • 1 1/2 C plum juice I made this juice by peeling fresh, farmers' market plums, cutting them up, and blending them. It was not 100% smooth and it was somewhat thick. But, it was super yummy! I'd tell you how many plums I used, but I actually forgot to write it down. Bad, bad.
  • 1 packet unflavored gelatin 1 T
  • 1/2 C boiling water
  • 1/4 C sugar
  • 1/8 t salt


  • Combine the gelatin with 1/4 C cold water in a medium bowl and let soften, 3 minutes.
  • Add the boiling water, sugar, and salt, and stir until the sugar dissolves.
  • Add the plum juice to the gelatin mixture and stir.
  • Pour into a 9 x 13 glass dish and chill.
  • When cool, cut out shapes with cookie cutters. While I used circles, you could use any fun shape you like!
