Food: How come this boss knows everything?

Chapter 72 Fried Cakes and Baked Sweet Potatoes
After choosing a place to sell snacks, Li Rui went to the vegetable market.

Here he also needs to buy some ingredients he needs.

Mainly red beans, glutinous rice flour (flour made from glutinous rice) and sweet potatoes.

Red bean filling and glutinous rice flour are the main ingredients needed for fried cakes.

They are all in the grain area.

The glutinous rice flour ground by water is more delicate and smooth.

After Li Rui bought the ready-made water-ground glutinous rice flour, he started to pick red beans.

When choosing red beans, you need to choose those that are bright in color, plump and round. Good appearance often means that the plant has sufficient photosynthesis time during its growth period and is well developed.

There are also ready-made red bean fillings on the market.

But Li Rui planned to buy red beans and make the filling himself.

The climate in autumn is dry and the temperature difference between morning and evening is large. Red beans have the effect of dispelling wind and clearing heat.

It is suitable to eat in this season.

For roasted sweet potatoes, Li Rui chose the Yanshu variety.

The spindle-shaped shape of the smoked potatoes is more uniform, and they are cooked through at almost the same time when baked in the same batch.

Moreover, the roasted smoked potatoes are full of honey oil, and the flesh is soft, glutinous, sweet and dense.

After baking, the gap between the skin and the sweet potato flesh makes the sweet potatoes very easy to peel.

Sweet potatoes are best eaten roasted.

Nowadays, tobacco potatoes are grown everywhere.

But in the birthplace of Yanshu, Yancheng City, Hedong Province, many local farmers choose to plant it in summer and harvest it in autumn.

Judging from the time, the newly harvested Hedong Province tobacco potatoes we buy now are most likely from Yancheng City.

There are many ways to choose yam on the Internet.

For example, some say that after the tobacco potato is cut at both ends, one end is red and the other end is yellow.

However, as sweet potatoes are plant rhizomes, as long as they grow vertically in the soil, they will inevitably be exposed to sunlight for different periods of time. This will happen to many varieties of sweet potatoes, and their moisture and nutrition will vary. This method is sometimes not accurate.

Some people also say that the surface of the sweet potato has "burst veins" (like the veins on the arm). But whether the surface of the sweet potato is smooth or not depends more on the material of the land where it is planted. This statement is also slightly inappropriate.

In fact, it is easier to infer from the origin of the tobacco potato.

The Yantai potato was cultivated in Yancheng City and has been promoted locally for a long time. It is very suitable for local cultivation.

Moreover, the yield of fresh potatoes is very high, and their economic value is more favored by local farmers than other varieties.

Farmers in Yancheng grow tobacco potatoes at low cost and high yield.

The tobacco grown in Yancheng will basically not be bad.

In addition to the above, he also bought some dried osmanthus to add to the bean paste filling.

After buying groceries, Li Rui returned to the shop in Fonda Plaza.

He looked at the time. It was just past nine o'clock.

The bean paste made today can be sold in the evening.

Red beans need to be washed, soaked in clean water for several hours, cooked, and fried. So they are processed in the first step.

Then he began to prepare the dough.

The dough for fried cakes is mainly made of glutinous rice flour, but Li Rui mixed a small amount of rice flour into the glutinous rice flour at a ratio of 9:1.

The rice flour serves as a crispy texture.

The fried cakes made in this way are crispier after frying, and are easier to chew after cooling down.

Li Rui added warm water into the basin and mixed the flour.

So I put it in the kitchen and let it ferment naturally for a few hours.

Naturally fermented flour has a unique fermented flavor, and the acidic components are neutralized with alkaline noodles (sodium carbonate) to make the flavor better.

Prepare the flour.

Li Rui called the smart butler:
"Xiaodong, Xiaodong, I need to ferment the dough in the kitchen, please help me control the temperature."

"Ok."

Next, start preparing to roast the sweet potatoes.

He placed the iron bucket given by the system on the dining car.

This metal barrel has never been used to hold gasoline, diesel or chemical raw materials, and lacks a sense of age. It is simply food-grade 304 stainless steel.

The heat source inside has also been changed from coal, which produces environmental pollution and harmful gases, to evenly coiled resistance wire.

The principle is exactly the same as that of an electric oven, but the appearance is made into a tin barrel.

In the past, you could often see sweet potatoes roasted in iron buckets on the streets.

The power of this iron barrel oven is 3kw, the battery of the dining car has a capacity of 60kwh, and the dining car has the function of reverse output of 220v voltage, so it is no problem to use it to bake sweet potatoes for several hours.

In fact, dining cars have a certain ability to serve food.

But the last time I used it, the lunch boxes were prepared in the shop and brought up.

This time you can fry fried cakes on the food truck. Fried cakes must be freshly fried to be delicious.

Li Rui cleaned up the dining car, put the kitchen utensils in place, and filled the water tank on top of the dining car's cab with water.

So I went back upstairs to rest.

At two o'clock in the afternoon, Li Rui woke up as soon as the alarm rang.

He went downstairs and into the kitchen. At this time, the beans were soaked. Li Rui put the red beans into the pressure cooker and pressed it for ten minutes to cook the beans.

Because the temperature for dough fermentation is set in the kitchen.

The temperature is 25°C and the humidity is 75%, just like a sauna. It is very uncomfortable to stay in.

Then you can make the red bean paste filling on the dining car.

Remember to buy an oven with fermentation function tomorrow.

Li Rui loaded all the food into the car and headed for the Workers' New Village.

When he arrived at the park, he didn't rush to open the business, but started busying himself in the dining car.

First, turn on the tin barrel oven and set it to 200 degrees.

Then he took out a Nanhai Huanghuali rolling pin, crushed the beans and osmanthus, and then added sesame oil.

Li Rui divided the mashed bean paste into three portions.

I will make the normal version with sugar, the version with xylitol, and a small amount of sugar-free version later.

Then heat the oil in a pan and start making the bean filling.

Wait until the bean filling absorbs the oil in the pot and becomes dense and sticky, then it's ready.

Everything is ready.

Li Rui opened the side panel of the dining car.

With the side panels open,

Li Rui saw many old men and women put away their curious looks and continued to look at the strange car with their peripheral vision.

Li Rui got out of the car and took out a small handwritten sign:
Baked sweet potatoes, 7 yuan per pound

Fried cake, 3 yuan a piece (with xylitol and without sugar)
The price of fried cakes reminded Li Rui of the steamed buns sold in the Jianghai University cafeteria, which cost 30 cents each and 1 yuan for three.

As the aroma of roasted sweet potatoes slowly wafted out and Li Rui called out a few times, the elderly friends near the park also began to talk about it.

"Selling fried cakes and roasted sweet potatoes. I thought it was doing something else."

"The roasted sweet potatoes do have a nice aroma."

Aunt Liu and Aunt Chen were both foodies when they were young, and they have never forgotten their original aspirations over the years.

"Look at this young man, he cleans up quite neatly."

"Sister Liu, I remember the state-owned food factory when we were young."

"Taste it?"

Soon, Li Rui welcomed the first batch of customers of the day.

"Aunties, what would you like to eat? The roasted sweet potatoes will have to wait a while, but the fried cakes are freshly made and fried."

"I'll buy two pieces of fried cakes. I'm old now and can't digest them if I eat too much."

"I'll have a fried cake and a roasted sweet potato, too."

"Just wait a moment."

The thing retired people have the most is time.
