Serving size: 1 glass (but easily adjustable!)
-1 orange, room-temperature
-passion fruit syrup
-cold carbonated water (Calistoga, San Pellegrino, club soda, etc.)
-ice (optional, but definitely nice if you have it)
- Juice the orange. Be impressed by how little juice is contained in that entire orange.
- Pour carbonated water into a glass until 2/3 - 3/4 full (this depends on how large your glass is).
- Pour in your fresh-squeezed orange juice. Be amused by how it fizzes.
- Add in a couple spoonfuls of passion fruit syrup. Stir a few times, to make sure everything's nicely mixed. Taste, then adjust sweetness and passion fruit flavor by adding a little more at a time until desired sweetness/passion is reached.
-If you want to make A LOT of this, it's probably most practical to just buy some (not from concentrate) orange juice.
-The proportion of carbonated water to juice is approximately 3:1. That means the final drink is 75% fizzy water, 25% OJ. If you're inaccurate like me, err on the side of more juice, less water.
-The reason temperature is specified for the orange and carbonated water (under ingredients) is...science-y! Sort of. I remember reading somewhere that you get the more juice out of citrus fruits when they are at room temperature than when they are cold from the fridge (there's some scientific reason, I can't articulate it). For the carbonated water, it comes down to gas laws: the colder it is, the more gas will dissolve into the liquid (something to do with molecular motion, I think...hey, chem was a long time ago..). The converse is also true: the warmer it is, the less gas will be dissolved in the liquid. This is why soda is so much more awesome cold. Essentially, for maximum fizziness, refrigerate carbonated beverages.
-I got the idea for this combo from a can of juice concentrate, haha...
-Orange juice + Sprite/7-up is also a most excellent combo. :3
