Background info: the couple of times I have been in China and tried to buy some food from shops, I have noticed that all the things on sale were already past their expiry date. When discussing this with a Chinese friend, I was told this is pretty normal and not to be worried about. We both live in Western Europe.
My question: Whenever this friend goes back to China, they always bring me some gift: usually it consists of cookies or other food, which is always past the expiry date. As long as it is dry food (cookies, tea), I have no problem giving it a try. However, when it's coated or stuffed items (like stuffed cookies) a couple of months or more past the expiry date, I am not willing to take the risk, though I have an hard time throwing it away (blame the education I was given).
How can I politely make clear that I am glad to receive and consume those gifts, but I would rather prefer them not being expired?
