Ingredients
1 package (3 ounces) lime gelatin4-1/2 cups boiling water, divided1 package (3 ounces) strawberry gelatin1 package (3 ounces) orange gelatin1-1/2 cups graham cracker crumbs1/2 cup sugar1/2 cup butter, melted1 envelope unflavored gelatin1/4 cup cold water1 cup pineapple juice1 carton (8 ounces) frozen whipped topping, thawed
Preparation
Combine lime gelatin and 1-1/2 cups boiling water; stir until gelatin is dissolved. Pour into a lightly greased 8x4-in. loaf pan; chill until very firm. Repeat to make the strawberry and orange gelatins in separate pans. Combine the crumbs, sugar and butter; press into a greased 13x9-in. dish. Chill.
Meanwhile, in a small bowl, soften unflavored gelatin in cold water for 5 minutes. In a small saucepan, bring pineapple juice to a boil. Stir in unflavored gelatin until dissolved. Transfer to a large bowl; set aside until room temperature, 20-30 minutes.
When flavored gelatins are firm, cut into 1/2-in. cubes. In a large bowl, whisk whipped topping into pineapple juice mixture. Gently fold 2/3 of the cubes into whipped topping mixture. Spoon over crust; top with the remaining cubes. Chill for at least 2 hours.
