First of all, the main material for making egg yolk puff pastry is lard. The lard suet on the market is nearly 10 yuan per kilogram. If you want to reduce the cost and sell it cheaply, just use 100 yuan to buy 30 kilograms of shortening...

Shortening is not much, usually It is used in French fries and fried chicken, but it usually contains trans fatty acids, which are harmful to the body

Let’s talk about the core of the egg yolk cake-the egg yolk. The cost of buying salted duck eggs directly with freshly cracked yolks is about 0.8 to 1.5 yuan. If you buy the more famous free-range duck salted duck eggs or sea duck eggs, the average price is about 1.8 to 2.3 yuan.

And directly If you buy vacuum-packed frozen egg yolks, the average price is as low as 0.4 yuan per egg.

Finally, there is the filling. If you buy vacuum-packed egg yolks, you still need to spend several hours cooking it by hand. In addition to the price, the taste and health are also different. There is also a significant difference in degree.

Take the commonly used red bean filling as an example. The price of red bean filling purchased directly from Moubao is about 15 yuan for 5 kilograms with free shipping, and it also costs 20 yuan for 1 kilogram depending on the quality. However, those who have higher quality requirements need to buy their own fillings and cook them, usually with red beans, sugar and other ingredients. In addition to the material cost, there is also a layer of manual cooking time cost.
