Jello flavors of your choiceI used Berry Blue, Orange, Raspberry and Lime
In a mixing bowl, combine the Junket Ice Cream Mix with the milk and heavy whipping cream. Mix until fully combined.
Pour the mixture into a bread/loaf pan or small 9x5 pan and freeze until it is firm.
Using a butter knife, carefully separate the cream into chunks, then put the chunks into a mixing bowl. With an electric mixer beat the chunks until smooth.
Divide the vanilla ice cream evenly into four different bowls using a spatula. Put ½ - 1 tablespoon of the different Jell-O powder flavors in each bowl and gently mix with a spoon until fully combined. Try and do this as fast as possible to prevent melting
Put the 4 different ice cream flavors together into a container that can be sealed. Using the back of a spoon or your spatula carefully connect the 4 different piles of ice cream so they freeze as 1 piece.
Freeze for another 1-2 hours to allow to fully set.
