With my initial order of diy supplies over a year ago, I was advised to use sweetener in the recipe. I've since tried a couple more flavors and again added sweetener. The first flavor I mixed was coconut and I liked it. The next 2 are fruit flavors and I can't stand them. Could the sweetener be making these fruit flavors too sweet? I've looked through a few recipes here and haven't come across any calling for sweetener. Isn't sweetener normally used in recipes?
