"I tried Ina's recipe for the first time this Thanksgiving and worked with around 5# of potatoes. I up adjusted some of the ingredients to allow for the additional pound of potatoes and the end dish turned out pretty well. I would add a word of caution on the 2 teaspoons of salt. Even with the additional pound of potatoes, the dish was noticeably salty. I would suggest starting with 1 teaspoon and adding additional salt to taste. I also made a topping mixture of graham crackers, brown sugar and pecans which I process in my food processor and sprinkled over the top. If it weren't for the salt factor I would have given this recipe 5-stars.
