I’ve been buying the big cans of gatorade powder lately because I’ve been busy and they are cheap. But they are still absurdly expensive for what is essentially just salt with food coloring and artificial flavor, and I dislike how much sugar it contains.

UNICEF website, it’s called ORU, Oral Rehydration…something. It’s designed to be made out in the field for cholera and dysentery patients. Best I can do. Very similar to the recipe posted in this thread by another lemming.
ORS - Oral Rehydration Salts
Found some reading on it both on UNICEF and WHO websites.
Thank you.
There you are!
UPDATE: I’m mixing that ORS with iced Yorkshire tea right now, just to prep to work outside. God bless all the Tartan Army in Miami, they should try this cultural appropriation.
