This is a classic Spanish potato side dish that can be served with a homemade lemon aioli sauce or light lemon mayonnaise. I've had this recipe for a while now, and I thought I should post it before it's lost forever. I stumbled onto it the first time a few years ago when I bought saffron to make a certain recipe that called for only a few threads. But I didn't want the saffron to go to waste, so I started searching for other recipes calling for saffron. And that's when I discovered this recipe. And I have made this recipe many times over the years. It makes an especially great side dish to accompany baked fish.
