Homemade yogurt

Remember when we were kids, we just moved out of the countryside. For children in cities, yogurt may be a common snack, but for us it's not even known. Until now, every time I drink yogurt, I remember the stupid way my sister and I first met yogurt. On that day, my sister came up with a dollar and said, "Well, I've often seen people drink that jar of milk, and they say it's yogurt, and it's good, or we'll have a taste of it?" When we drink the first yogurt, it's like it's broken, and we're face-to-face, and that's what everyone says about the delicious yogurt? It's a broken milk! But when we couldn't throw it away, we swallowed our heads, but the more we drank it, the worse it was, the more we couldn't stand it, the more we scolded the poor man's boss and sold us the broken milk, the more we beat our children from the countryside, the more we couldn't get rid of the yogurt. It's so funny now. The yogurt this time is made of powdered milk and tastes good。
