So I followed
So about an hour later, it was finally ready. As I started breaking it open, I worried a little. Okay, a lot. The only orange food I've ever eaten before were cupcakes on Halloween. Never had squash, never had pumpkin, never had, well, sweet potato or yam. And it was really, really orange. Bright orange.
So I added butter (more than I usually would for potato) and cinnamon and (though Shadowfey didn't list it) a tiny bit of nutmeg (someone online mentioned adding it). I had no brown sugar, so that had to be left out.
My thought at this point was: Mmm, smells like Thanksgiving! I took that to be a good sign.
So it was time to taste it! Bravely I took a whole forkful, not just a little nibble like I usually do with new things. It was fine and dandy. Dare I say good? It tasted like normal (though extra buttery) potatoes, just a little sweeter.
So yay! The experiment was a success! Especially in winter, when I won't mind leaving the oven on for an hour, this will be a fine meal (or part of a meal). I'll probably continue to leave out the sugar and cut way back on the butter, but other than that, it's in.
Now, if only I knew if it was the yam or the sweet potato...
