"Sweetie, can we just put this in our mouths and eat it?"

Su Muyao nodded. "This is the cream ice cream I told you about a few days ago."

Upon hearing this, Su Laosan subconsciously swallowed.

A few days ago, I was complaining about how hot the weather was, and my little daughter said she would make me cream ice cream in a couple of days. She said it would be so delicious, cool and sweet.

Now that we have cream and ice, making cream ice cream is much simpler.

Su Muyao then directed her father to cut up a large basin of watermelon.

I poured a whole basin of watermelon into the juicer, and soon bright red watermelon juice appeared in the machine.

Long Yuan couldn't take his eyes off the machine, sometimes looking at the watermelon juice that was automatically coming out, and sometimes at the blocks of ice.

There was also the refrigerator that Su Muyao tiptoed to open, and cold air was emanating from inside.

I put the prepared cream in the refrigerator, and after a while I took it out and started scooping out the cream ice cream.

Su Muyao put the ice into the machine, and soon a bowl of cool shaved ice was freshly made.

I took several extra-large mangoes from the space and placed them in the kitchen; each one was the size of my head.

When Grandma Su saw Su Muyao carrying a yellow fruit that was almost the size of her head and about to walk into the main room, she quickly took it from her arms.

"Wow, it's so big! If you ever need this kind of work again, have your dad do it."

"Okay, Grandma, let's go try the new food I made."

Upon hearing this, Grandma Su immediately chuckled and said, "Good, good, good! I'm so lucky! My darling always thinks of Grandma. Grandma is so blessed."

Su Muyao scooped the finished ice cream into a paper bowl and handed it to Long Yuan.

Longyuan scooped up a large spoonful of mango ice cream, put it in his mouth, and the next second his eyes widened in disbelief as he took another big bite.

"Poor child, he's never had anything good to eat in his life," Su Muyao sighed from the side.

But what she was really thinking was, "Yaoyao, I've seen a lot of things."

Seeing that Long Yuan liked it, Old Man Su finally calmed down. It was good that the Crown Prince liked it.

Soon, the entire Su family fell in love with this stuff.

On a hot summer day, being able to eat a bowl of ice-cold ice cream is simply a treat.

Thinking about the large freezers in the space, it seems that I can use the knowledge I learned in my previous life, as well as the dessert books in my space, to open another summer carnival shop.

Their huge storefront could easily be divided into three shops.

Lately, Su Laosan has also developed a business mindset. The first thing he thought when he saw ice cream was whether it could be sold for money.

Especially in the sweltering summer, this product is sure to sell like hotcakes once it hits the market.

"Honey, do you think we can sell this?"

Su Muyao nodded. "It's possible, but it's a little troublesome to do. If you want to open a shop, you'll need to find more people, otherwise you won't be able to handle it."

Yingyi arrived late at this time. When Su Muyao saw that it was an old acquaintance, she quickly handed a portion to Yingyi as well.

As soon as he picked up the bowl of ice cream, Shadow One immediately sensed something was wrong.

"What is this? Is it ice?" I asked in confusion, because the bowl I was holding was unusually icy.

"Try it, this is called ice cream, I made it myself."

Long Yuan looked at his guard, who was still staring longingly at the bowl in his hand. He wished he could just snatch it and eat it himself.

After everyone had tasted all the desserts, they unanimously agreed that it was time to introduce new items.

While it was still early, I went to the village where the villagers gathered and found a few young women that I liked.

These young wives all come from families with many children, and in most of these families, the father-in-law or mother-in-law has already passed away while fleeing famine.

Explain your labor needs to these people: the wage is three taels of silver per month, but the workday is six hours, or 12 hours.

Of course, I also made it clear to them that it might be tiring and that there would be verbal communication with the guests.

These people quickly agreed, and before long, the young wives had gathered in Su Muyao's courtyard.

Su Muyao took out several large basins and began explaining to the people how to make ice.

Seeing that Long Yuan and the others didn't seem to be leaving, he didn't bother to chase them away. After all, they were the Crown Prince, and he couldn't go too far.

Of course, I also believe that a prince of a country would not steal the recipe of a little girl from a farmer's family.

The women were quite curious when they heard that ice was going to be made. When they learned that they would have to sign a confidentiality agreement, they were already familiar with it and quickly pressed their fingerprints on it.

"Making ice requires saltpeter. Just add it to the water step by step, and it will freeze into ice after a while."

In reality, Su Muyao was just putting on a show; she didn't intend for all the ice she sold later to be made with saltpeter.

There are plenty of ice makers in the space, and with the refrigerators, freezers, and the ice already stored there, there's no need to use saltpeter to make ice.

Ice made from saltpeter shouldn't be consumed in large quantities, which is why I don't sell the recipe but instead sell the ice.

It takes about ten pounds of well water to make ice, but saltpeter can only make a small portion of edible ice.

Saltpeter can be reused; you just need to evaporate the water to extract it, but it's a huge waste of firewood and time.

This was also the result Su Muyao initially obtained by experimenting with the book.

The water temperature from the deep well was about 17 or 18 degrees Celsius. She added about 18 kilograms of saltpeter to 50 kilograms of water to produce about 10 kilograms of cool water at about 4 or 5 degrees Celsius.

They then added about two pounds of saltpeter to the ten-odd pounds of cold water, which finally melted the two pounds of water in the iron basin into ice.

If you keep pouring saltpeter into the large basin until the water in the iron basin freezes, you'll consume too much saltpeter.

This gradient cooling method is the most economical way to use nitrates.

In fact, almost every time-travel novel contains a method for making ice, and the plot of getting rich overnight involves selling a pound of ice for tens or hundreds of coins.

They're all making a fortune, with demand exceeding supply.

But once you actually do it, you'll realize that it's just a way to earn a meager living.

Putting aside everything else, just thinking about the workload of extracting so much saltpeter from the water every day is terrifying.

Fortunately, the capital city is full of high-ranking officials and nobles, otherwise who would have such spending power?

Think about it, ordinary people wouldn't spend a lot of money to buy such consumables. A household would probably consume at least 50 kilograms a day.

"My dear daughter, this saltpeter isn't cheap. How much do you plan to sell it for per pound?"

Su Muyao had also considered the price. She didn't intend to actually make it with saltpeter; she could make an endless supply of ice.

Therefore, the price cannot be set too high; it must be affordable for ordinary people.
