I told a 50-year-old master. Anyway, steam is good. Let's compare their differences. First, the gas produced by the steam boiler is constant temperature. Don't burn the pot. They say the cauldron tastes good, but they don't understand. The taste of the cauldron is fragrant. Why is it fragrant? Because when the soybean milk is cooked in an iron pan, the soybean milk will stick to the cauldron continuously, producing a large amount of pot gab, giving off a burnt smell and stringing it into the soybean milk. Tastes like burnt incense. In fact, this ointment is the most harmful to people. It is the kind of pot gab that constantly produces harmful gas sulfur dioxide, which enters soybean milk and blood flow to supply the brain. Damage to cardiovascular and cerebrovascular diseases. Eating tofu in a big pot for a long time will lead to Alzheimer's disease, cardiovascular and cerebrovascular diseases. Dizziness. Gross. I said eat more. The second is that steam is more hygienic than cauldron. Try the ash from burning coal in the tofu cauldron, and the stove pit is equipped with a blower. You can imagine when you blow. There is dust everywhere. Fall into soybean milk. Third, the nutritional value of steamed tofu and soybean milk is higher than that of cauldron. Because of the constant combustion in the production process. A lot of nutrients are wasted. The last paragraph is for everyone. I often think that tofu in a large pot is more delicious than steamed tofu. You are too ignorant to pretend to understand. What you eat is not the smell of tofu, but the harmful gas that harms your health.
