Dragon Fruit Cake
Try to find pink-fleshed dragon fruit. White is more common, but the pink one gives the frosting the nice pink hue.
Simple syrup is an equal mixture of sugar and water, cooked over high heat until it comes to a boil.
Leftover dragon fruit puree keeps well in the refrigerator for up to five days and can be used as a topping for ice cream or oatmeal or to make smoothies.
