The grocer had organic sweet potatoes in stock, so I took advantage and brought some home. I'm freezing them for winter meals.
Yesterday, I baked several, then allowed them to cool completely. I added a bit of water and organic broth to the pan. I pierced each sweet potato a few times before placing in the covered pan.
After I removed the foil, I sliced each sweet potato in half to cool faster. I removed the skin, mashed them, and froze them in individual servings.
I did not add anything to the sweet potatoes. Five sweet potatoes gave me 5 - 1 cup servings.
If you have frozen sweet potatoes with added ingredients, I'd love to know how they turned out and tasted.
