They've been having a run on fresh baby octopus at the local supermarket. So, I am trying a lot of menus. I think that baby octopus has more nuance of flavor than the mature variety. There are some other recipes listed on site I plan to try, once I acquire the rest of the needed ingredients. Yes, you can use any variety of potato you have at hand, but Yukon Gold seems to trump just about any other I've run into, in terms of flavor. Play around with liquid quantities: it really does depend on the size of cooking pot. Ponzu sauce: this is a Japanese sauce based on soy, but with a citrus overlay. Most supermarkets carry it.
