To avoid using the oven, I made this no-bake sweet potato "casserole" by simply boiling 2 chopped sweet potatoes. Then I mashed it (still in the pot) and added a few tablespoons of brown sugar, 1/4 tsp cinnamon and 1 tsp vanilla. After mixing, I smoothed it into the pie plate and added the marshmallows on top. (Which were frozen- yes, I freeze my marshmallows so they don't get all mushy in this Florida heat!) Voila! No butter, no baking, but tastes just as great.
These are all the sweet potatoes I used for these two dishes. The small ones on the right are from our sweet potato plant. Yes, you can grown this in a 5 gallon bucket! I don't know how long I should have kept them in there to get them to grow as big as the store bought. But it was amazing to pull them out of the bucket.
