About the Recipe
This recipe is very forgiving and can be replaced customized to your taste and flavor. Instead of using almond or oat flour it can be substituted with rice flour or whole wheat. The milk can be replaced with any milk of your choice as well as the sugar. You can also use any type of sweet potato or yams that you have. In the picture I used a purple yam and a white yam. You can choose to roast, steam, or boil your potatoes/yams until they are cooked through. I personally like to roast mine due to the caramelization that it gives the potatoes.
