Of course, there are many audiences for Sichuan cuisine, but as long as you mention the name, most people will be able to reflect it at first sight.
But how widespread is Shandong cuisine? It's a lot of your familiar home cooking, which is generally considered by most people as "national unity". If you explore their roots, you will find that many of them are Shandong cuisine.
Don't believe me, if nothing else, I will give two typical examples: scrambled eggs with tomatoes and braised chicken.
Are you surprised? You may ask, "Isn't this home cooking?" Yes, as I said just now, many Shandong dishes have become so common that people think they are "nationally unified". Authentic scrambled eggs with tomatoes, Shandong cuisine style is very strong: that is, fresh and salty, with the sweet and sour of tomatoes, very appetizing. Note that scrambled eggs with tomatoes with sugar are all adapted from other provinces. The old-fashioned practices inherited in Shandong Province do not put sugar, and their sweet and sour taste depends entirely on the effect of tomatoes themselves. This also means that the selection of tomatoes is very strict. Of course, tomatoes that are too sour can only be fried sour, and of course they can only make up for the "sweetness" by adding sugar. However, the sweetness and sweetness created by this method is a suture, which is obviously better than that of high-quality tomatoes.
