When I was in high school one of the women where my dad worked brought some of this and he liked it so much that he got the recipe. I think this was one of the first times I had tried sweet potatoes without marshmallows (gag) and loved this. I used to make this with all purpose flour and regular milk and was one of the competitors in a sweet potato cook-off my family did here . Since we have gone gluten-free it is not something we can eat anymore so we remade the recipe. It tastes just as good as the original but is gluten-free and dairy-free. We have reduced the amount of sugar in the topping and increased the sweet potatoes to make it less sweet. Plus we made it gluten-free and dairy free and something we could all eat.
