A bottle of Ocean Spray Cranberry Juice Cocktail (cheap store brands just don’t work for this, I think they probably have a lot of water in them)
Frozen orange juice concentrate (the large one, they come in two sizes)
Grab a container with a lid that’s freezer safe. I always use some sort of plastic for this recipe, like Tupperware. Dump in the entire container of cranberry juice into your container then add the frozen OJ concentrate. You may want to let it sit at room temp for about 30 minutes, that will help with mixing the OJ in. Depending on how strong you want it, fill the emptied frozen OJ can from 1/2 to completely full with vodka. Mix everything together well then put a lid on it and pop it in the freezer for overnight. The next day, scoop it into glasses and serve it with a spoon. The alcohol keeps the juice from freezing solid. It comes out like shaved ice and is super yummy.
