When the expectant bangs left, Li Chengqian fell into depression again.

There is no other reason, that is, he, a person who claims to be able to make cakes, is now defeated by raw materials, in his previous life, he could make cakes, that is ready-made raw materials, as long as they are processed according to a certain proportion, but now they want white sugar without white sugar, and they want cream without cream, how can this be played.

Although in later generations, as long as you have a little common sense, you will know that white sugar is refined from brown sugar, and cream is made from milk, but the problem is to let him tell how it is refined, nine out of ten people are confused, and one is either to ask Du Niang, or someone in the family does this, otherwise ordinary people will know.

So people living in the future are happy, you don't need to know what the principle of all kinds of daily necessities, there are a large number of finished products in the supermarket, and you don't have to be like Li Chengqian now, if you want to eat well, you have to make it yourself, and you start from the source, this still accounts for the benefits of Li Chengqian's identity, otherwise in this life, but for a food and clothing for him to fight for many years, not to mention, just get something out, and worry about whether it will be robbed by the strong, or even lead to death.

In this way, Li Chengqian locked himself in the study and thought about it for a long time, but he didn't come up with any good way, until Xiao Yi'er came back and played there with a piece of silk, Li Chengqian remembered that the reason why brown sugar is red and dark red is because when it was made, it was just simply filtered, so it would be better if the brown sugar was filtered a few more times.

Thinking of this, Li Chengqian immediately asked people to find a large amount of brown sugar, as well as fine gauze and silk, and directly set up a cauldron in front of the lobby of the East Palace and boiled brown sugar there.

Boil and filter it over and over again, although the color of the brown syrup is lighter, but there is still no substantial change, which makes Li Chengqian very frustrated, just when Li Chengqian was about to give up, no matter what broke the brown sugar, Mo Cheng came over with a finished oven.

"Your Highness, what are you doing here, what kind of good things are boiling in that pot" Mo Cheng saw Li Chengqian, and after greeting him, he saw that Li Chengqian had just come from the cauldron boiling brown sugar, and asked curiously.

"It's nothing, this king is boiling brown sugar there, Mo Lao, you say, there is nothing in this world that can absorb the color?" Seeing Mo Cheng coming to say goodbye, Li Chengqian said to him extremely depressed.

"This highness is the right person, the old decay really has something that can melt the color of the water, and the water with this bone meal, not only will the water become pure and transparent, filter out the bone meal, people can drink it directly without boiling, and they will not have stomach trouble" Looking at Li Chengqian's depressed appearance, Mo Cheng didn't hide it, and directly told Li Chengqian about the bone meal.

After Li Chengqian heard this, he looked at Mo Cheng with wide eyes.

"Mo Lao, you are not wrong, this is really bone powder, how do I feel the same as activated charcoal, no, I want to see how the effect is, you always give me some points" After speaking, Li Chengqian looked at Mo Cheng.

At this time, Li Chengqian's heart was excited, if this is true, then the sugar will be fine, and looking at Mo Chengcheng's expressions, nine times out of ten it is true.

As for why he thinks it is activated carbon, it is not in the previous life, all kinds of businesses are using activated carbon for advertising, and it is impossible to see it every day.

Of course, Mo Cheng would not object to Li Chengqian's request, and immediately asked people to go back and get bone meal.

Later, while waiting, Mo Cheng also told Li Chengqian how bone meal (bone meal, that is, bone carbon, which is used by sugar factories to bleach brown sugar and make white sugar) was made, and all the processes were made.

It turned out that the bone meal was made by Mo Cheng when he was teaching his disciples to make pottery and firing kilns, and his apprentices were greedy and put a big beef bone into it, and originally wanted to bake it and eat it, but he didn't expect it to be burned directly to ashes in the end.

Mo Cheng also beat the apprentice for this, but that's it, so Mo Cheng found that the powder made from the burnt beef bones can remove the magazines and colors in the water, and finally this bone powder has also become a kind of standing item used by the children of the Mo family to filter water when they go out.

After the others brought the bone meal from the workshop, Li Chengqian couldn't wait to take the bone meal and walk to the cooled brown sugar syrup, and after asking people to add some water to it, he took out some of the bone meal and put it in.

At first, there was no change, but after Li Chengqian asked people to stir slowly, a magical scene appeared, the originally dark red brown syrup water was slowly turning white, and finally the brown syrup water in the pot completely turned into a snow-white color

All the people who saw this scene widened their eyes, and they couldn't believe that there was such a magical thing in the world, but the facts in front of them made them have to believe it.

"Why are you still stunned, hurry up and filter these syrup water several times, and then boil it, and when it is thick, pour it into a hurried container and let it cool" Li Chengqian, who was the first to react, shouted to the eunuchs who were still stunned.

But before Li Chengqian could be happy for a while, Xiao Yi'er, who was already waiting for a lot of boredom, ran at him dissatisfied and shouted, "Brother, didn't you say that as long as Xiao Yi'er obediently goes to study, my brother will play with Xiao Yi'er?" ”

"Xiao Yi'er, I'm sorry, isn't my brother busy with business? But now that I'm done, how about my brother take Xiao Yi'er to make cakes, that's fun" Li Chengqian hugged Xiao Yi'er in his arms and comforted him.

However, Li Chengqian's comfort didn't seem to have any effect, and the little girl's eyes stared at the syrup water in the pot, as if asking why the color was wrong.

And Mo Cheng, who had been standing aside, looked curiously at the pair of brothers and sisters in front of him who were noble, but like peasant brothers and sisters.

As for the people of the East Palace, they have long been used to it.

Li Chengqian saw Xiao Yi'er looking at the syrup water curiously, and his eyes suddenly lit up, "Xiao Anzi is going to get a pot, come to those brown sugars"

"Xiao Yi'er, are you curious about why the brown sugar water here has turned white" After instructing Xiao Anzi to do something, Li Chengqian said to Xiao Yi'er in his arms.

"Well, Xiao Yi'er wants to know, can my brother tell Xiao Yi'er?" Hearing her brother's words, Xiao Yi'er stared at her big eyes and nodded to her brother seriously.

Looking at Xiao Yi'er's full curiosity and desire for knowledge, as well as her cute appearance, Li Chengqian's blood groove instantly emptied half of it, and she hugged Xiao Yi'er's little face and kissed her fiercely, which provoked Xiao Yi'er to giggle in Li Chengqian's arms.

"Brother, you haven't answered Xiao Yi'er yet, will you tell Xiao Yi'er" After laughing for a while, Xiao Yi'er asked again.

"Of course I will tell Xiao Yi'er, and after a while, my brother will let Xiao Yi'er do it himself, turning the red brown sugar water into white," Li Chengqian said to Xiao Yi'er affectionately.
