1 piece of tin foil

Recipe practice:

1. Choose a sweet potato of similar size, wash it and dry it. (Not too big, not easy to bake)

2. Put tin foil on the baking tray and put sweet potatoes on it.

3. Put it in a preheated oven and bake at 220 degrees for about 50 to 60 minutes.

4. You don't have to guard. Turn over every ten or twenty minutes when you see the surface is black, and turn over two or three times in the middle.

5. Sweet potato will ooze sugar juice during baking. It's time to take it out and crush it with your hands.

6. Red-heart sweet potato is sweet, and smells a little caramel on the skin, which is very fragrant.

7. To sum up, the baked sweet potato is divided into three steps, washed, put in the oven and taken out.
