If the freezer in the refrigerator is not cold enough, the freezing speed of yogurt will be slower. If the freezer of the refrigerator is low enough, the freezing speed of yogurt will be faster. Different freezing rooms have different freezing speeds.

If you want to quickly freeze yogurt, you can prepare some cold-boiled yogurt, then put it in a container, put it in the freezer of the refrigerator, and then take it out for 5 minutes, so you can quickly freeze yogurt by repeating it several times.
