The water is too hot and the temperature is too high, which is the main cause of cracking.
I also use 150 degrees, but I have to bake it for 75-80 minutes, which is an 8-inch round mold.
I usually observe it when it is baked for 40-45 minutes.
If the water in the water tray is bubbling and the temperature of the water is very high, add cold water.
If it's not so hot, don't add it first. . .
But if you say, "oven 160 degree preheating, lower layer, water bath method, after a few minutes, it bulges a little."
2, in a few minutes, cracked. "
That is, it cracked before adding water, right?
In principle, you shouldn't take a water bath, it won't crack so quickly. .
Among them, adding water twice to cool down is also to prevent cracking. . Let me think again. .
However, I think it is already very good, and the crack is not serious.
Or do it a few more times and find out why.
It took me two months to get my temper in my oven,
The oven is different from the oven, too. I use the copied recipe, which says 180 degrees. If I bake it, it will break down.
Later, I tried 170, 160 and 150 step by step, and finally found out the reason.
Another reason is that if you are too close to the fire, the temperature will come up quickly, and you will put it in the lower layer.
That's why this is happening. I used to let the lower level go, but later I only let it go to the middle level.
