Sufuli is a transliteration of SOUFFLE. In fact, it is a kind of cake baked with batter made of beaten egg whites mixed with milk, which is light and soft after baking and has a very crisp texture. The taste can be salty (such as CHEESE SOUFFLE and broccoli SOUFFLE for punctuality) and sweet (such as ORANGE SOUFFLE for dessert mentioned in the book). The reason why Xibao says it is the most difficult to make is not for other reasons, because the raw materials are ordinary eggs, butter, flour, sugar, etc. (in fact, all kinds of dough in West Point are changed from different formulas of these basic raw materials), and the process is similar to other cakes, but what is special about SOUFFLE is that it is very, very delicate-it is not easy to make it swell into a beautiful shape in a cup (there are many tips in it) In the process of baking, the temperature and heat are not wrong at all, and the control in this respect is even so strict that you can't even open the oven halfway to check, because the temperature change caused by the convection of hot and cold air will also make this rose-frothy SOUFFLE collapse, thus making people give up all their efforts. Finally, when baking is finished, you should be very careful (it's best to close the doors and windows). In case you come to through flow for a while, that's too bad ... That's why Xibao has to personally take it out of the furnace.

I won't elaborate on the practice. The above is very clear from my dear friend. In addition, it is necessary to add that the baking tool used is preferably a special oven, not a non-professional microwave oven with barbecue function.
