Qiao Xiaoru shook his head and smiled: "It's still early, these starches are still a little thick, and we have to continue to wash them." ”

After all, it is the most primitive method to obtain sweet potato starch, which is inevitably mixed with a lot of impurities.

Fortunately, the impurities are lighter than starch, and they are all on the top layer.

Qiao Xiaoru instructed to scoop out the layer of starch with impurities on the surface, and the layer of starch on the surface was also brown and yellow because of the impurities.

She remembered very well that the sweet potato starch she got in the end should be whiter in color.

Lu Xing'er, Mangosteen and others were distressed.

In other words, although it is mixed with a little impurities, this is also the starch that has been obtained with great difficulty, so wouldn't it be a pity to throw it away?

Qiao Xiaoru laughed, "Do you think delicious food is so easy to make?" If the starch is filled with impurities, the taste of the things made will be greatly reduced, and the gains outweigh the losses. ”

Lu Xing'er sighed reluctantly and scraped off the starch mixed with impurities.

The next step is to add water, continue to add more than half a jar of water, and then stir with a long wooden stick the size of an egg to mix all the starch with the water.

After stirring completely, the added water has already become cloudy, still the same brownish yellow, but the color is lighter than the previous tank of water.

"Okay, when the starch settles, then get the water out, and the layer of impurities on it must be scraped off. After the starch settles, when will the water in this tank become clear, and when will the starch be used! Qiao Xiaoru said with a smile.

Does this jar of water get clear? Everyone was skeptical.

After the water in this tank was changed, the water was changed again the next morning.

The same is the same as before, scoop out the water, scrape off the top layer of starch mixed with impurities, add water, stir, precipitate, and change the water......

The next day, I changed the water four times.

Every time you change the water, the brownish yellow color becomes a little lighter.

On the third day, when they were about to change the water early in the morning, everyone took the covered bamboo sieve and looked at it, and couldn't help but be surprised, "Ah! "Up.

I saw that the water in the tank was very clear, and the starch below could be clearly seen through the water.

"Xiaoru, this is it, right?"

"Lady Qiao, look, this water has cleared!"

"yes, yes, it's amazing! The water was mixed like that yesterday, but who knew that it would become so clear in just one day's work. ”

Qiao Xiaoru looked at it, nodded and smiled: "Well, it's okay, you get rid of the water, you don't need to add more water." ”

The crowd cheered and got busy.

Next, it's time to get the powder.

The starch must be dried in the sun for easy access and storage.

It just so happens that the weather is very good at this time, the sun is bright, and it is enough to bask in the sun for two days.

When they had scooped the water dry, they scraped off all the starch and put it in a basin.

Qiao Xiaoru stretched out her hand and pinched it, the starch was very smooth and delicate, with a faint fragrance. Smelling the fragrance, he felt a sense of familiarity that he had not seen for a long time, Qiao Xiaoru hooked his lips and smiled, and his heart was soft.

Once the starch has been dried, you can start making sweet potato flour.

Dried sweet potato flour can be made into hot and sour noodles, can be put in the oven, all the ways to eat noodles sweet potato noodles are suitable, noodles are not suitable for eating sweet potato noodles are also suitable. That's a real goodie.

Subconsciously thought of Lu Zhan, Qiao Xiaoru couldn't help but feel hot in her heart.

How good it would be if he was there, she actually cared a little bit, and hoped that there would be no shortage of him in such a fulfilling day.

It's just that at this time, he should already be in Yichun County, right?

Qiao Xiaoru unconsciously looked up at the distant horizon, everything is still going well in Yichun County? When will he be back?

Break the wet sweet potato starch and crush it, spread it out in a dustpan and expose it to the sun.

Two days later, it was as scheduled.

Qiao Xiaoru asked someone to put all the starch into a clean flour bag and weighed it, a total of sixty catties.

In other words, a hundred catties of sweet potatoes can get a little more than twenty catties of sweet potato starch.

Qiao Xiaoru is very satisfied with this result.

In this day and age, sweet potatoes are not valuable, unlike in modern times, they are highly sought after as a coarse grain that is extremely beneficial to the body.

In the harvest season, one penny can buy three catties, and on weekdays, one penny can buy two catties.

According to the calculation of two catties per penny, one hundred catties is only fifty catties.

And 100 catties of sweet potatoes can produce 20 catties of starch, and 20 catties of vermicelli can be made.

In this era, the price of an ordinary pound of white noodles is ten yuan, but sweet potato vermicelli is a new thing, even if it is ten yuan a catty, twenty catties is two hundred yuan.

Excluding costs and labor costs, one hundred wen is definitely earned.

And, this is the most conservative algorithm.

She planted so many sweet potatoes in her own land, the cost of this piece can be saved a lot, and the price of the sweet potato noodles made must be higher than that of noodles at the beginning......

Looking at this delicate and smooth sweet potato powder, Qiao Xiaoru had already calculated it in his heart.

After that, the sweet potato flour is packed and stored in the warehouse.

The next day, I took ten pounds and started to try it.

After adding water and noodles, it is generally said that sweet potato flour is mixed into a dough, and after it is fully blended, it is put into a leaky basin with small holes the size of chopsticks at the bottom, and the handle of the leaky basin is held firmly with both hands and shakes back and forth on the boiling pot, and the vermicelli will leak down from the small holes and quickly form in the boiling water boiling pot.

Then take out the vermicelli with a special long chopstick, put it in a basin filled with cold water to cool, and then cut it into the same length as long and short, hang it on a bamboo pole, and rest it in a cool place to set the shape.

At this time, it cannot be exposed to the sun, and it must be left in the shade overnight before being exposed to the sun the next day.

Everyone watched the process of food formation step by step, and the mood was fresh and exciting.

The big kitchen was full of laughter and laughter, so lively, everyone was full of interest and scrambling to do it.

Fortunately, the kitchen is big enough and doesn't look cramped.

Even Ji Lianjin's guy, first rushed to make noodles, and then he thought it was fun to leak the basin, and he wanted to operate it when he grabbed the leaky basin.

Qiao Xiaoru only sat calmly and smiled and watched, silently counting in her heart: one, two, three......

Before he counted to twenty, Ji Lianjin hurriedly lost the battle, and in the laughter and jokes of everyone, he gave the leaky basin to Mo Shi.

Qiao Xiaoru is also funny, not to mention that Ji Lianjin's body is still recovering, even if it has returned to normal, this kind of work is not something that a person like him can do.

In such a hot weather, there is fire and boiling water vapor by the stove, and the hands hold such a large leaky basin in their hands and keep moving, this is not an easy job.
