Method for making purple potato grandma cake
The old woman cake is a traditional Chinese cake, which originated in Chaozhou, Guangdong. It is a kind of Chaozhou moon cake, and it is also a pastry snack with less materials, relatively simple production and high popularity.

Authentic old lady cakes are made of glutinous rice flour and wax gourd sauce unique to Chaozhou. The old lady's cake made of this stuffing is thin and thick, soft and moist, crisp outside and tender inside, soft but not greasy, and it is very delicious to bite.

The old lady's cake is delicious, but many people don't know why they call it the old lady's cake. There is a short story about the origin of its name.

There was a teahouse in the late Qing Dynasty, which was famous for all kinds of snacks. One day, the owner of Chaozhou Teahouse brought some signature refreshments home for his wife to eat. His wife didn't praise it after eating it, but said it tasted just so-so, not as delicious as her parents' melon horns.

The master was not convinced and asked his wife to make it for him. She made it with wax gourd sauce, flour and sugar. After eating it, the master really thought it was delicious and praised this snack for its delicious taste. The next day, he took this snack to the owner of the teahouse to taste it. The host praised it and asked who did it. The master said his wife did it. The boss blurted out that it was called Chaozhou old woman cake. This is the origin of the old lady's cake.

Whether as a snack or as a pastry, the old lady's cake is a Chinese pastry. The main production material is flour. The choice of flour will affect the taste of cakes. This snack is very crisp. It is certain to use flour with low protein content. This kind of flour is low in gluten, and the cakes made will be soft or crisp.

In the choice of flour, many novice friends are very confused, thinking that flour is the same, but in fact they are completely different.

Flour is the main raw material for making Chinese dim sum and western pastry. In the process of cake making, flour can be divided into three categories according to the content of protein: high gluten flour, medium gluten flour and low gluten flour. High gluten flour, also known as bread flour, has the highest content of protein, ranging from 12% to 15%. It is suitable for making bread and cakes.

Low-gluten flour, also known as cake flour, has a minimum protein content of 7%-9% and is suitable for making cakes and biscuits.

Medium gluten flour is a kind of flour between high gluten and low gluten, and it is a common flour for daily consumption. Protein content is 9%- 1 1%, which is generally used to make steamed bread, rolls, pancakes and some Chinese pasta.

Different flours have different uses. Understanding the differences between them is very important for making all kinds of cakes successfully. To make this kind of Chinese dim sum cake, flour should be used according to the situation. For example, glove film should be rubbed out on the oil skin. It is recommended to use medium-gluten flour, while low-gluten flour is difficult to rub out the film, and the crisp part is the key to crisp taste, so it is necessary to use low-gluten flour, so that the old cakes made will be crisp and sweet and delicious.

It is best to use lard to make old lady cakes. The taste of lard is incomparable to any oil, but many people reject the taste of lard. The old woman cake made of vegetable oil instead of lard will have a hard taste and no lard or butter flavor. If you really don't like lard, share a butter version of the old lady's cake. The thick butter tastes more fragrant when chewed, which is different from the old lady cake made of lard.

Need material water and oil skin part:

225g of common flour, 80g of butter (which can be replaced by the same amount of lard and vegetable oil), 45g of fine sugar and 90g of water.

Crispy part:

180g low-gluten flour and 90g butter.

Filled parts:

Appropriate amount of bean paste stuffing (white gourd paste, purple potato paste, lotus seed paste and other fillings can be used)

Surface decoration:

Egg yolk 1, black sesame proper amount.

The first step of making: after preparing the materials, start making the water-oil skin, put all the materials in the water-oil skin into a basin, stir them evenly, and then knead them evenly to get the glove film. Authentic old woman cakes are made of lard, which makes them easier to come out of the glove film and tastes softer, but the oily smell of lard is unacceptable to many people, so you can use the same amount of butter or tasteless edible oil (such as corn oil, sunflower oil, olive oil, etc.). ) on the contrary. After kneading the dough, cover it with plastic wrap and relax for 30 minutes. Butter must be softened at room temperature before use.

Step 2: Next, make the crispy part, put the low-gluten flour and butter into a basin, press and mix it into a ball with a scraper, then cover it with plastic wrap and put it in the refrigerator for refrigeration. It is recommended not to use hands to knead dough, because the temperature of hands is relatively high and it is easy to melt butter.

Step 3: After the dough is relaxed, knead it into long strips and divide it into 20 equal parts, each of which is about 23g. Cover it with plastic wrap for later use. Then divide the dough into 20 equal portions, each of which is about 65,438+07g. Take one portion and press it into dough by hand, and then wrap it in another portion. When wrapping, push the dough upward with a tiger's mouth. Finally, press the dough into dough by hand.

Step 4: After all preparations are wrapped, cover with plastic wrap and relax for 15 minutes. After relaxation, make the first crisp, take one of the preparations, roll it into a beef tongue with the mouth facing up, roll it up from top to bottom with the palm of your hand, and then place it face down. After all preparations are made, continue to cover with plastic wrap and relax for 10 minutes. After relaxation, the second opening is the same as the first opening. After everything is finished, continue to cover with plastic wrap and relax for 10 minute.

Step 5: After relaxing, take a pill, press the middle with your index finger, and butt the two ends. Pay attention to whether the butt joint is folded in half, press it into a cake by hand, pack 30 grams of bean paste stuffing, put it down, and then gently flatten it into a cake with your palm. An old woman's cake embryo is ready.
