I've tried a homemade recipe for it, but can I just show you something first?
Real containers for Chinese take-out. I was ridiculously pleased with this, especially since I'm running low on tupperware.
Okay, I found a recipe here that I decided to try. True to the author's word, it's not as sweet as a box mix. It's not too bad and I don't mind that's it not so sweet, but I probably won't use this again. Still good, so it's not going to waste, but not quite where I want it to be. Also, if you make this, make sure you have a big enough container. I had to resort to using a 2 quart drink container. It makes nearly a quart of dry powder.
