Slippery Circles

Pour the water into a medium saucepan and bring to a boil over medium-high heat.

Remove the saucepan from heat and sprinkle the 3 envelopes of unflavored gelatin over the water, stirring constantly until completely dissolved, about 1-2 minutes.

Stir in the thawed frozen grape juice concentrate until well combined.

Pour the gelatin mixture into a shallow 8x8-inch pan or baking dish and refrigerate for 30 minutes, or until it reaches a gel-like consistency but is still slightly soft.

Slice the banana into thin rounds, approximately ¼ inch thick.

Using a round cookie cutter or drinking glass, cut circles out of the partially set gelatin.

Arrange the banana slices on top of each gelatin circle, pressing gently so they adhere.

Return the pan to the refrigerator and chill for 2-3 hours until the gelatin is completely set and firm.

Turn the pan upside down onto a cutting board or serving platter and gently tap to release the gelatin circles with banana toppings.

Serve chilled, or gently remove each circle individually with a spatula and arrange on serving plates.
