Is the method of making tofu brain the same all year round? What does this have to do with the weather? Why can't it rain now? (lactone point)

I'll tell you what lactone does in different weather. It can be poured when it is cold to 80-90 degrees in hot weather. When cooking in winter, it can be irrigated in spring and autumn. It's that simple. I have been doing this for decades. Please give me some advice.
