Beautiful potato dish! I was surprised at how easy this dish was to put together...great instructions! I cubed the potatoes and then boiled them as Pot Scrubber did. The onions were such a great complement to this dish as was the garnish - I would not forgo the garnish. The sauce was excellent. The only thing i did differently was to add serrano peppers to the cheese sauce.
A very nice dish with a lovely flavor. I didn't change the ingredients at all but I did vary the cooking technique. I cubed the potatos and boiled. After the sauce was ready I assembled it in a casserole dish, topped with additional cheese, and baked at 400 til the cheese melted. A very nice mexican version scalloped potatoes.
