It is still recommended that LZ use butter. I have seen it on the blog of baking master Jun Zhi before. He said that the puffs made with salad oil have very thin skins and become soft easily. Collapse. But the puffs made with butter are different. The puff skin made with butter is more complete, the shape is better, and the taste is more fragrant. I read on his blog that he recommended the French President's butter. After thinking about it for a long time, I finally bought it and made some puffs. Sure enough, the golden puffs exuded the alluring milky fragrance of the President's butter. I couldn't hold it back. Eat too much~~
