500g fresh watermelon
1 package of unflavored powder gelatin

1 cup milk
1 package of unflavored powder gelatin
1/3 cup sugar
A pinch of salt
1 tsp vanilla extract
2 cups heavy cream

Place in a food processor, pulse until smooth. Transfer it to another bowl and sprinkle gelatin on top. Gently stir until well incorporated and let it sit for 10 minutes.
Now place the gelatin mixture in the microwave and heat for 1 minute on high. Stir until gelatin completely dissolved.
Prepare glasses and place them in a mini muffin pan at an angle.
Carefully pour the watermelon mixture into each glass until almost to the edge of each glass.
Place in the fridge for at least 2 hours, or until set.
While waiting for it to get firm, in a small sauce pan, place milk and sprinkle gelatin on top. Give it a quick stir and let the mixture sit for 10 minutes. When 10 minutes is up, turn on the heat to low, add sugar and salt and constantly stir and heat until gelatin completely dissolves.
Remove from heat and whisk in vanilla extract.
Now pour this mixture over heavy cream and give it a quick stir.
Take the cups with the watermelon layer out of the fridge. Pour the vanilla mixture into each cup.
Return it to the refrigerator to chill for another 2 hours, or until set.
