1. Wash the potatoes and cut them into 0.5cm pieces without cutting off the bottom. When cutting, pad two chopsticks on the bottom.
2. Wrap it with tin paper. In the oven, 250 degrees, middle, up and down the fire, about 30 minutes.
3. The specific time should be based on your own oven. When it's about the same time, you can pinch it. If it feels soft, you can.
4. Then peel off the tin paper, cut the bacon into proper size, add cumin powder, salt and olive oil and mix well.
5. Put it into each potato. Sprinkle another layer of cumin powder and salt, and brush with olive oil.
6. Reenter the oven and no longer wrap. 200 degrees, about 15 minutes.
