* I used a high quality frozen passion fruit concentrate here. To use this product, dilute the concentrate with water (1:1 ratio), then measure out for the recipe. If you'd like to use fresh passion fruit, you'll need 8 to 10 fruits. Passion fruit can be hard to find and often expensive when you do find them, so I'd recommend getting a contain of the frozen puree. It lasts a long time, and the flavor is just as good.
