Hi: I take ONE packet Knox gelatin, ONE packet unsweetened Kool-Aid...7 Packets splenda sweetner, and ONE cup HOT water....mix in bowl...then add ONE cup COLD water...mix...put in cups...into fridge...makes jello!

Others have said use two packets knox...It work just as well with one packet, and is not as thick like a chunk of plastic. One packet KNox makes it like real jello.

Hope this helps!
Best wishes;
Jake
