This is not their “secret” recipe, but it is a pretty good stab at a replication. If you’re craving guri-guri and can’t get to Maui, try this at home:
3 cups strawberry guava juice or pineapple juice*
1 ½ cups 7 UP® or other lemon-lime soda (let )
1 can (14 oz.) sweetened condensed milk
By hand (takes at least 24 hours):
Combine all ingredients in a large bowl and combine thoroughly. Freeze for about 1-2 hours, remove from freezer and stir again, making sure to beat all ice crystals back into the mixture. Freeze again for 1-2 hours and beat again. Repeat at least once more. Scoop partially frozen mixture into freezer-proof containers for individual servings. Freeze at least eight hours (a day is better) until firm.
By ice cream maker:
Combine all ingredients in large bowl and combine thoroughly. Pour into ice cream maker and freeze per manufacturer’s instructions.
*You can use any flavor of juice that appeals to you – please post your success stories below. Also, try coconut milk. Just remember that the juice will be combined with super sweet condensed milk.
