1. Insufficient or excessive fermentation of dough: fermentation time and temperature are very important. If the dough is not fermented enough, the buns will look loose. If the fermentation is excessive, the bread will become too soft and taste bad.

2. The viscosity of the dough is too large or too small: if the dough is too sticky, it may not be able to spread and ferment normally. Dough that is too dry or too hard is easily broken when it is cut or squeezed.

3. The baking time is insufficient or too long: If the baking time is insufficient, the bread will turn yellow or deform. If the baking time is too long, the bread will become hard and lose its taste.

4. The oven temperature is too high or too low: If the oven temperature is incorrect, it may cause the surface of the bread to burn or become too dry, but the inside is not mature.

5. The amount of honey added in the dough is insufficient: honey is the key ingredient of honey buns, but if the amount is insufficient, the taste of bread may not be sweet enough.
