Dissolve the grape gelatin in 150 ml of hot water and mix in 150 ml of ice water.
Pour half (150 ml) into a decorated pan with a hole in the middle (microwave pudding pan is ideal), greased with oil.
Place in the freezer for 10 minutes, or until slightly hardened.
Mix in the other part (150 ml) 6 tablespoons of condensed milk and 4 tablespoons of coconut milk.
Place on top of the other carefully along the walls of the form, take it to harden again a little in the freezer, about 15 minutes.
Repeat the same process with the other jellies, in order of flavors (to give color contrast).
Finally, cover with cling film and refrigerate for 6 hours.
Unmold and serve.
