Kool-Aid as my flavoring, a similar flavor is their Blue Raspberry Lemonade. I then used my best scientific skills to put together a taste test for my wife to compare. I call it double-blind, because I didn't know what I was doing and she didn't know what it should taste like. The results were that she liked my recipe better than the original. Hooray!
Here is my recipe for a 2 quart batch which cost about $0.65 (65 cents) a quart. Using table sugar would cut that price down significantly, but would raise the carbohydrates. My recipe has about 2 grams of carbohydrates per 1 cup serving, using sugar raises that to about 15 grams per cup.
Gus and Sandy's Gatorade
64 fluid ounces of water
1 packet of Kool-Aid of your favorite flavor *
8 single serve packets of Stevia **
1/4 teaspoon table salt (sodium)
1/8 teaspoon Morton Lite Salt (potassium)
In a juice pitcher add 1/2 the water. Add all the ingredients and stir. Add the rest of the water, stir again, refrigerate and serve.
* 1 cup of 100% fruit juice can be used as a substitute for flavor.
** sugar or honey can be used as a sweetener substitute depending on your dietary restrictions and taste.
Special acknowledgement - To my sweet wife Sandy for being a good sport, so she gets her name on the recipe too! Thank you Honey.
End Note: I just realized now that my special recipe is just sugar free Kool-Aid with a pinch of salt. LOL. I'm such a nerd, but it's special to me!
