This was not a success. It was bland, even though added extra garlic and some broccoli. The egg/sour-cream mixture did not soak down through the rest of the layers; it just stayed on top like a shiny, eggy unappealing crust. Furthermore, the prep time was far too low; the potatoes took much longer to cook since I cooked them whole as in the instructions. I would not make this again, unless I made major adjustments, starting with mixing together the elements, instead of using layers.
