Does the subject want to ask the oven temperature and time of 250 grams of toast, and what is the reason for the wet wrinkles under the toast? The oven temperature is 180℃-200℃, and the time is about 10- 15 minutes. The reasons for wet wrinkles at the bottom are as follows:

1, the oven temperature is not high enough or the baking time is not long enough, so the toast is not completely cooked.

2. The humidity inside the oven is too high, which leads to the dry surface of the toast and the humidity inside.

3. The surface of toast is not coated with butter, olive oil and other oils, resulting in dry surface and wet inside.

There is too much moisture in the dough, which makes the bottom wet when baking bread.
