In the 21st century, the commonly used units of measurement in various countries are grams and kilograms.

However, the concept of "gram" was only proposed in 1795. At that time, Gaul defined it as the "absolute weight of water at the melting temperature of ice, with a capacity equal to a cube with a side length of one-hundredth of a meter."

Therefore, in the 17th century, the commonly used units of measurement in England were still the customary system, such as drams, ounces, and pounds.

In the customary system, one ounce is approximately equal to 28.3495 grams, while in the troy system, it is 31.1034768 grams.

When Xu Yun mentioned ten ounces, it was a little over 280 grams, about half a catty.

As mentioned earlier.

The cost of making tomato sauce mainly lies in sugar. About 30 grams of sugar is needed for one kilogram of tomato sauce, which is roughly equivalent to 18 ounces of sugar.

Currently, the market price of sugar is about 8 pence per 100 grams, but the cost price for the parish is much lower, probably only about 2 pence—this can be compared to the internal price of tobacco or liquor. Sugar is even more ruthless because it is a plundered item.

Therefore, after conversion, the cost of ten ounces of tomato sauce is approximately 0.6 pence.

Including transportation, labor, and miscellaneous expenses, it is about 0.8 pence.

With a cost of 0.8 pence, the selling price is 2 pence, which is actually considered cheap—according to normal thinking, under the premise that others can quickly replicate the product and enter the market, the higher the price, the better.

But the Grantham Parish is not a professional business association after all. The cloak of religion determines that they cannot deceive people too much, otherwise, it would not be worth the loss.

Therefore, after some discussion, Arlin finally set the price of tomato sauce at two pence for ten ounces.

When the market settles down in the future, this premium will not be criticized too harshly—just use the blessing buff if necessary... cough, cough.

"Ten ounces for two pence..."

Upon hearing Xu Yun's offer, Tiffany Boli quickly calculated in her mind:

The current per capita income in England is 0.65 Gini, which is about 150 pence. On average, one can earn a penny every two days.

Tiffany Boli's family has a slightly higher income than ordinary families. They can settle in Grantham, and the annual income of the whole family is about 1.2 Gini.

With this in mind, Tiffany Boli looked at the jar next to her and asked, "Is this one jar ten ounces?"

Xu Yun nodded, "Yes, it is the standard weight of ten ounces."

Tiffany Boli nodded slightly.

Ten ounces (280 grams) of tomato sauce looks like a lot, even if it is used to spread on bread or dip potatoes every day, it probably won't be finished in less than ten days or half a month.

It is more expensive than butter, but much cheaper than sugar. Even an ordinary family can afford it.

Therefore, after a moment of hesitation, Tiffany Boli made up her mind:

"Sir, please give me ten ounces."

"Alright!"

Xu Yun quickly took out a bottle and said in a low voice, "Madam, this bottle is freshly made tomato sauce, taken from the back. It is fresher than the others. Please don't tell anyone."

Tiffany Boli was originally thinking about whether she could negotiate the price, but when she heard this, she was delighted—she saw it very clearly that Xu Yun did indeed take the jar from the back area.

So she didn't negotiate the price anymore and handed over two pence happily, saying, "Thank you very much. Please keep these two pence."

Xu Yun politely took the money and handed it to the parishioners next to him, watching them record the transaction.

Then he looked around and, taking advantage of the gap when no one came over, stuffed a jar of tomato sauce into the empty space behind...

Just as Xu Yun finished this covert operation, someone suddenly touched his left arm.

Xu Yun turned around and found a little girl about the size of a bean standing beside him, not knowing when she had come.

Naturally, the one who can walk around here freely is none other than William's daughter, Lilani.

But this time, Lilani was not holding cow dung, but a cup of steaming hot water.

Xu Yun blinked and seemed to understand something. He pointed at himself and asked, "Is this for me?"

Lilani nodded.

Seeing this, Xu Yun couldn't help but feel a little surprised:

Has this mischievous child become more low-key and well-behaved since the last time they met?

This is also good—it's not that girls must be quiet and conform to the traditional virtues, but at least they shouldn't be mischievous.

Then he took the cup of water and took the opportunity to blow on it. After scanning it, he found that there was no random stuff added to it, so he took a sip:

"Thank you, Lilani."

Lilani remained silent for a few seconds, and then a word popped out of her mouth:

"Sorry... for last time."

After speaking, this former mischievous child turned around and ran away with small steps.

Xu Yun couldn't help but scratch his head:

"This child..."

..........

Tiffany Boli's purchasing process is just a microcosm of today's stall. With the guarantee of the parish, William's family hardly needs to spend much effort to easily sell jars of tomato sauce.

Taste test—introduction—payment.

The whole process is that simple.

Three hours later, today's market entered its final stage—this is only the end of today, according to custom, the market will continue to open for one day tomorrow.

The Church of St. Theodore will temporarily provide an internal area for the merchants to stay overnight.In a certain sense, this was somewhat like a future exhibition that included accommodation, a method led by the government to stimulate the economy.

Just as Xu Yun was preparing to help clean up the venue, Little Newton mysteriously pulled him aside:

"Fat Fish, we're going to be rich!"

Seeing the gold-starred eyes of this old man, Xu Yun's curiosity was piqued:

"Oh? Mr. Newton, how much tomato sauce did we sell today?"

Little Newton glanced around cautiously and whispered a number:

"Nine hundred pounds!"

Hearing this number, even Xu Yun couldn't help but smack his lips:

"Goodness, nine hundred pounds?"

Nine hundred pounds, that's over fourteen thousand ounces.

According to the ten ounces per can specification set by William and his team, that's over fourteen hundred cans of tomato sauce.

You have to understand.

The permanent population of the entire Gransum main city is only 3-4 thousand people, even during the market period, the population gathered is just over twenty thousand.

More importantly, a can of tomato sauce corresponds not to one person, but to a family!

Even if we deduct some cases of wealthy people buying repeatedly, the purchase rate of this tomato sauce will not be less than 15%!

From this, one can imagine how big a market tomato sauce will have in the whole of Europe - of course, that adjective should not be ignored, a market that cannot be monopolized.

"The cost of a can of tomato sauce is 0.8 pennies, the net profit is 1.2 pennies......."

At this moment, Little Newton's small brain, which could rank among the top in history, began calculating basic math in a very mercenary manner:

"1400x1.2 is 1680, divided by 252 is 6.67 gini, we get 30% of that which is 2.2.....

Oh God, it's only been three hours, it's only one Gransum! How long can a can of tomato sauce feed a family?"

In his excitement, Little Newton slapped Xu Yun's shoulder heavily:

"Fat Fish, I hereby declare, we are friends now!"

Little Newton's slap was a bit forceful, and Xu Yun almost stumbled unprepared.

"Can you be a bit gentler..."

Xu Yun grumbled and rubbed his shoulder, just about to lift his head

When he felt a pause around him, and a long-lost prompt appeared in front of him:

[Newton has regarded 'Wall-Facer' as a good friend, the novice task has been completed, the instance time has stopped, and you will return to reality soon!]

Xu Yun:

"????"
