I’ve recently discovered the loveliness of Quinoa, and the joy of buying it in bulk at Costco, so I’ll be making a lot of it in the near future.  I’m wondering if I can use my rice cooker to make the Quinoa. Has anybody done this? Does the ‘fuzzy’ logic in the machine prevent it from doing anything other than cooking rice and steaming veggies? I hope not, but I also don’t want to ruin a good kitchen tool finding out either. Thanks! 
I've cooked white rice, brown rice, wild rice, whole Oat Groats (2 brown rice cycles + a little extra water on cycle two) , rye groats, Khorasan wheat (kamut), barley, Spelt, and numerous other seeds in my fuzzy logic rice cooker, but never Quinoa. It seems to me the white Quinoa seed benefits from a short cook time, and a long post-cooking expansion time. A rice cooker doesn't do that very well. The red Quinoa I can also get is tougher, and might like being cooked like brown rice. That said, I haven't tried it. It's certainly possible that your rice cooker could make passable Quinoa. I suggest you give it a try on a small batch. If you like the result, post that here, and I'll try it too.
