Remove from the heat and add the gelatin. Stir until it begins to thicken. Let it sit for 10-15 minutes before adding the strawberries, stirring to combine.

Add the Manischewitz to a small saucepan. Heat until it begins to simmer. Remove from the heat, and add the gelatin, stirring to dissolve. Let sit for 20-30 minutes while you finish assembling.

Add the blueberries to the final layer, stirring to combine. Pour over the almost set white layer and add to the mold. Refrigerate until set and ready to serve.
