– Used Greek yogurt instead of sour cream – still delicious.
– I think I’ll use a ricer next time. These need a fine texture to the potato. Using a masher or mixer still leaves big enough chunks to ruin the texture.
– This may be a peculiarity of my slow-cooker, but three hours was too long. The sides started to burn after two hours, so I stopped it then.
– I’m going to try it with three egg whites next time. I really like the lightness they brought to the dish.

Really delicious dish and such a good idea!
