A refreshing tropical smoothie that will bring in the sunshine no matter what time of year it is. Made from raspberries, mango, passion fruit, and orange. You can use fresh or frozen fruit here. Frozen is more convenient and it gives the smoothie a nice frosty texture, but if you have really delicious ripe, fresh fruit then by all means use it! (Add a few ice cubes though to make sure the smoothie is nice and chilled.) Making the smoothie in two batches is just for appearance sake to make the layers. You can blend everything all together if you don't need a sunrise mimicked in your glass.
