Each country has its own habits, some of which will make foreign tourists completely unintelligible. For example, Egypt, if you go to the Egyptian home guests in their own meal to add salt, is a very rude thing. This makes a lot of tourists do not understand, food with salt is not a very normal thing, but in Egypt this is a taboo.
It is well known that Egyptians are very hospitable and good at all kinds of cooking. But Egyptians have their own obsession with cooking, and that is to be very confident in their own cuisine. Therefore, when you are lucky enough to travel to Egypt, especially when you go to someone's house for dinner, do not add salt to your own bowl or the guests' bowl, adding salt to this action will be the Egyptians default to the chef's disrespect. Maybe you just feel uncomfortable taste, but for the chef, it means that you do not recognize my dishes, a kind of white hard feeling. But after thinking about it, it's not unreasonable. It's like when you go to eat a Western steak, and they've paired it with salt and pepper for you, but you must ask the Western restaurant to add some more Sriracha, which is indeed not very polite.
But fortunately, Egyptian cuisine is still relatively tasty without the extra salt . While it's normal for us Chinese to put salt in our food for a lighter taste, it doesn't really help when you combine it with the local cooking methods and ingredients. The Egyptians have a heavy diet, and their cuisine is thick and spicy, with salt and pepper and even curry in the seasonings. Egyptians and themselves also prefer to eat beef and mutton, especially the kind of Arab barbecue, the material is no money to put in the dish. So don't say extra salt, a lot of Egyptian natives with light tastes, have to specially urge the chef to add a little less salt.
So, Egyptian food does not intentionally add salt, is the recognition of the cook and respect. It can be seen, in fact, each country has its own table manners, out of traveling before the guests, be sure to do the relevant homework in advance, to understand the local flavor, or may be out of order.
