    My mother has made these for years and we all loved them! The only difference is that we never used flour. My mashed potatoes are lumpier than most (we love them this way) so you get more chunky potato bits!

    I am so excited to try this recipe. My mother would use left over mashed potatoes to make potato pancakes, but sadly I never got the recipe or watched her make them.So I haven’t tried this recipe but will as soon as I have some leftovers. Thanks!
