This is based off of fresh passionfruit juice from our garden. Fruit will vary in sweetness/tartness so adjust amount and sugar amount to taste. This is pretty tasty as a cocktail with the addition of rum and a bit more lime.
There are different varieties of passion fruit, some much less tart and sweeter than others. Adjust sugar for different varieties and to taste.
If you are a pulp-free type, make a mint simple syrup (see Note 2) instead of muddling the mint leaves and sugar.
Add passion fruit juice and water to the muddled mix. (Add passion fruit seeds if you are so inclined) Divide into 2 glasses filled with ice.
*Note 1: Extracting Passion Fruit Juice
Cut the passion fruit in half then scrap out the seeds and pulp into a small mesh strainer. Over a small bowl to catch the juice, scrap the seeds and pulp using the back of a spoon in order to separate the pulp and juice from the seeds. Reserve the seeds if you enjoy them in your drinks or other recipes.
*Note 2: Mint Simple Syrup
(keeps quite well, so make more than needed and use for iced tea, making lemonade, cocktails, etc...)
Combine 2 cups (480ml) water, 2 cups (400g) sugar, and a large handful of mint leaves in a medium saucepan. Heat just until a light simmer, stirring to dissolve sugar. Remove from heat and allow mint to steep for 15-20 minutes. Strain and store in refrigerator until ready to use.
