March 15 is Elsa's birthday.

The place is the big cafeteria in the institute in Horai Island.

"Happy birthday, Elsa.

"Thank you, Brother Jin."

Happy birthday!

Happy birthday!

On the island of Horai, the Jin family was celebrating his birthday together.

On a large table covered with a white tablecloth was a large birthday cake.

Perid and his family had painstakingly completed this cake.

The most difficult part was the sponge cake.

Jin did not know how to make it, so it took many trials and errors.

It took him several times until he realized that he should use light flour.

If you don't sift the flour, it will be lumpy, if you don't whisk it properly, it won't expand, etc. Several times before he tried adding butter and milk as well as flour, eggs, and sugar.

Then, after adding the butter and milk, it takes about a dozen times. Dozens of times to find the best mixing ratio, baking temperature, baking time, and so on.

The fish in the fish pond ate the failed ones. It is a relief that they did not go to waste.

Next to sponge cake, whipped cream was the most difficult to make.

For some reason, they had never made cream, even though they had a culture of making cheese.

The fat content of milk is usually around 4 grams per 100 grams (depending on the season). Therefore, even after centrifugation, only a small amount of cream can be obtained.

This is probably why cream was not eaten in the Arus world.

For the same reason, butter was not widely used.

As a side note, cheese is made mainly in mountain villages like Mochto in the Kingdom of Elias.

The basic cheese is cottage cheese made by adding vinegar to warmed milk to separate the protein content.

The use of lactic acid bacteria seeds called "bulk starter" increases the variety.

A quick aside.

This cake is made with a lot of airbert (strawberries), Elsa's favorite.

This cake is full of the fragrance of spring.

"Woohoo!"

"Brilliant!"

Elsa is applauded for blowing out the beeswax candle in one breath.

"Thank you, ....... I'm going to go now."

Elsa herself cut the huge whole cake into pieces.

"Yes, it's delicious.

"If Reinhardt says so, this wine is a winner."

Reinhardt took a sip of the sparkling wine Marcia brought and seemed to like it.

"Most sparkling wines are sweet, but this one is on the dry side.

In Ars, sparkling wine is often made sweeter for women and children.

"It's delicious."

Elsa is drinking a non-alcoholic sparkling juice.

It is made from the juice of ripe bitis (grapes) and carbonated.

"It's delicious!"

Hannah seemed to like this taste too.

"No, I didn't know there was such a wine!"

Count Luis Wurtz Kuzma, a nobleman from the Kingdom of Egelea, Blueland, also praised the wine.

"I didn't know this was made by an unknown winemaker!"

Yes, a wine made by an up-and-coming winery, unnamed.

"This wine tastes better than the wine served at Prince Ernest's birthday party the other night!

Louis had attended the birthday party in the capital.

"We should promote more industry in our country. ......"

He glanced over at Beena, one of the standard-bearers of industrial promotion.

"Topopo chips are good, too."

Bina, who is pregnant and strictly forbidden to drink alcohol, is sipping a Ramon squash (lemon juice mixed with carbonated water and added sugar) and eating snacks. Her stomach was becoming more and more prominent.

"Oh yes, thanks for the other day, Gin. The caramelized popcorn you taught me about is going over very well.

"That's good to know."

It seems that selling not only salty foods, but also sweet foods has been well received by a wider range of customers.

These foods and magic tools are stimulating the industrial world of the Kingdom of Egelea in a positive way.

"And you want to see your grandchildren, don't you?

"Yes, well. But this is the only thing that even Jin-sama can ...... do."

"Well, it's a gift, so I can't say for sure.

In the corner, Milowina, Meane, and Martha were talking about something.

Jin instinctively decided it was best to stay away and moved in the opposite direction.

"Jin, this is delicious!

"Jin-sama, you're so cute!"

Marikka, it's not polite to talk with food in your mouth.

Zion and Marikka were enjoying fried chicken ...... or deep fried kokarisk.

Elsa is not fond of kokarisk, but today she has prepared it for her guests.

I have used several different spices so that you can enjoy the different aromas.

Don't eat too much. There will be more to come."

"Yes."

True to their word, the golem maids appeared with trays of food on them.

"Here they come!

"Wow!"

Sushi dishes such as Gomokuzushi, Inarizushi, and Kappamaki. No nigiri-zushi this time, as it is not to everyone's liking.

Rice dishes such as sekihan (red rice), rice cooked with wild vegetables, and rice cooked with chestnuts.

Sandwiches, jam buns, pancakes.

"I can't get enough!"

"Eat whatever you like, as much as you like. We also have tea.

Green tea, hojicha, genmaicha, taeye, kuhe, percha.

"I think she likes porridge."

Bertsche is spoon-feeding porridge to Juliana, whom she has brought with her.

"She can even stand up and walk now," she says.

I can't take my eyes off her.

"She's so cute!"

Stearina and Vivienne are looking after Juliana.

"It tastes like old times..."

Guth muttered to himself as he ate the rice with wild vegetables.

"Did Mitsuho and Fusoh have okowa?"

Jin heard him muttering and asked.

"Yes, they did. They didn't taste as good, though."

It was not as good as this." This is not surprising in a culture where rice and rice cakes are available.

"But I never thought of putting maruon in it.

"I see."

As a lover of chestnut rice, Jin could not miss this dish, which was somewhat surprising.

"I think it's also because there are not many maruons in the market."

Guth gave his own analysis.

Reiko took pictures of everyone enjoying themselves with her camera. It seems that she has already taken more than a hundred pictures.

Jin goes to Erza's side when the time is right.

"Ah, Jin-bro!"

Elsa was eating cake at her own pace.

"I'm having fun today."

"Yes, it is."

Jin went outside with Erza.

The sun was shining softly and the sky was blue.

Spring has already come to Horai Island, which is located on the Tropic of Cancer.
