I received a SodaStream carbonator as a present. Once the main flavor samples and the (low-charge) CO2 canister were used up, I wondered what I could do in my own kitchen for flavorings. After seeing http://www.instructables.com/id/Homemade-Vanilla-Cream-Soda/, I thought about what flavors I could reproduce, or at least semi-synthesize.

So, here is a recipe for a diet grapefruit soda. I call it Frasca, because a) the name is close enough to that commercial product without blatantly violating copyright, and b) just call it a tribute to the designers and manufacturers of those fine Frasca general aviation flight simulators.

Step 1: Acquire Foodstuffs and Tools


1 medium grapefruit
2 cups Splenda or other suitable sweetener
SodaStream straight-up seltzer


Hand or sieve
spatula or other stirring tool
Is it possible then to make a ginger/lime/tulsi flavor soda by just boiling the prior with some sugar then sodastreaming it?
I'm not acquainted with tulsi (at least I wasn't, until I looked it up on teh internetz just now). I'd probably treat your flavoring as tea. Try this: <br> <br>Bring a little water to a boil, add ginger, lime zest, and tulsi to the boiling water, stop boil, let this mixture steep as you would tea (the tulsi and ginger may take longer than tea to infuse the water--experiment). <br> <br>In a separate pan, make your sugar/water syrup, adding the lime juice to the sugar syrup. Strain ginger/lime zest/tulsi mix into sugar syrup, mix, let cool. <br> <br>Sodastream some water, add a small amount of the mix to a glass, add seltzer to glass. See elsewhere for ChuCraft's Instructable on SodaStream mixes, and how she uses an old SS bottle for measuring out: https://www.instructables.com/id/Make-your-own-Sodamix/
That's a good idea as well, ancienthart. I thought I would experiment first, with existing fruits and such in the pantry (hence the use of grapefruit), before looking at cordial concentrates. I'll look into fruit cordial recipes. Thanks!
My wife and I make plain soda water with our SodaStream, and pour it over concentrate cordials from the shop. In Australia we have a couple of very nice ones made by Bunderberg Ginger.<br>Maybe an easier route for you would be to make some home-made fruit cordials instead of soda syrups?
