Exercise:
1. Prepare a flat plate, put it in the freezer in advance, and freeze it for 15 minutes.
2. Pour two bags of yogurt into a bowl, add all the above materials and stir well.
3. Take out the pre-frozen plate and pour the stirred yogurt into the plate. Because the two tastes are different, pour them separately and smooth the yogurt solution with a shovel.
4. Put it in the freezer for 30 minutes, then take it out, shovel it up with a shovel and break it (it depends on whether it is frozen hard here, if not, until it can be shoveled out), and then put it in the freezer for 5 minutes (shovel it into pieces).
5. After taking out, the sheet will be harder. Turn it over a few times with a shovel and put it back in the freezer. After freezing for 3 minutes, take out the shovel and put it in a bowl.
