This was incredibly lemony and EXTREMELY sweet. It real is more of a dessert than a side.
I don't know why so many reviewers suggest adding cinammon--the flavor is so lemony nothing else is needed and I doubt cinammon/nutmeg would go with the lemon.
Also not sure why so many people roast the potatoes. I followed the recipe and the pie (it's not a casserole) came out perfectly cooked.
Try it! Enjoy.
