Walter.
Step-by-step explanation:
In the process of baking and cooking of the pastries or pies, if there is too much handling done then it can cause the walter to develop a little more than what is actually needed.
It would lead to over developing of the dish which might be pastries and the pies. This might change and make the taste of the pastries and the pies turn bad and not what was expected out of them to taste.
