I traveled back to ancient times, but I was able to lie down and relax.

Song Chen shook his head, somewhat helpless, but resignedly went to think about a name for the shop.

Liu Nanjia presented a difficult problem, but researching new products is no easy task.

Now that the store is open and customers are eating there, the costs naturally increase, including rent, tableware, cleaning, and so on. The money and labor required have all increased.

So she plans to raise the price slightly.

Then we can't simply serve the original fried chicken to the customers, as that would cause dissatisfaction.

So she decided to make a sauce.

Originally, her favorite Korean fried chicken was always coated in sauce, and there were many different flavors. Even the simplest fast food restaurant kind came with ketchup.

To be honest, the fried chicken she's selling now is not something you can eat too much of; it gets very greasy very easily.

It's because the people here don't eat much oily food that they're so popular.

But how exactly do you make this sauce?

The two most common ingredients, tomatoes and chili peppers, are nowhere to be found.

this is a big problem.

There are other new items as well. Since we already have fried chicken and bread, Liu Nanjia decided to continue this Western fast food menu and make a hamburger.

The bread is ready-made; we just need to bake some more that are the right size.

For the middle layer, we'll start with fried chicken, and then we can see how it goes before launching other products.

But fried chicken is of course different from what we have now. It can't be as small as popcorn chicken, and the chicken legs need to be processed a little more, with the bones removed.

So Liu Nanjia made two versions: one was a boneless chicken leg burger, and the other was a chicken cutlet burger made by pounding a whole chicken breast into the shape of a chicken cutlet.

Then, just like the hamburgers I've had before, I added a leafy green.

She couldn't quite replicate the sauce, so she added some pickled cabbage to half of it to cut through the richness. It was homemade by Aunt Wang and brought to them.

It tastes a bit like the pickles that are sometimes added to hamburgers. Some people like it, and some don't, so she added half of it for them to try.

I also sprinkled some pepper and other powders on the fried chicken, which is a basic version of chili powder.

That day, their dinner consisted of the hamburgers that Liu Nanjia had made. The rest of the Liu family members became taste testers, not only having to eat them but also carefully sharing their feelings about which one was delicious and why.

At Liu Nanjia's insistence, Song Chen and the others had no choice but to savor the food carefully.

"I think it's better with pickled cabbage; it helps to balance out the greasiness of the fried chicken." This was Song Chen.

"I don't really like it; it feels weird to have it in there," Liu Yanxi said, holding the opposite opinion.

"It's spicy, so spicy! Sister, give me some water."

Liu Nanjia forgot that Liu Sirou couldn't eat spicy food and forgot to make a separate serving for her. Now she hurriedly went to find her some water.

As for the chicken, they were quite in agreement, all thinking that chicken thigh meat was tastier.

And so, the first new product was decided – the chicken leg burger.

Depending on the customer's needs, they can choose to add or omit the pickled cabbage, and there are also spicy and non-spicy versions.

Liu Nanjia actually had some regrets; there was another important ingredient in the burger: salad dressing.

If we can make it, we won't need sauerkraut.

As it is now, Liu Yanxi and the others who haven't tried the original version will think it's pretty good, but she herself is somewhat dissatisfied, however, there's no time today.

So during their December holidays, the family didn't go out much; they spent most of their time researching new products.

The main task was for Liu Nanjia to research how to make salad dressing.

Finally, as the saying goes, "Heaven helps those who help themselves," and she actually managed to produce something almost identical.

Whisk egg yolks with sugar until fluffy, then gradually add oil while stirring slowly until the mixture becomes slightly thick.

Because she remembered that the sauce had a slightly sour taste and was used to cut through the richness, she added white vinegar and continued stirring.

When it finally turned into a pale yellow color, it really did look quite similar.

Liu Nanjia let the others taste the burger with salad dressing, and this time it received unanimous praise. Even Liu Yanxi, who said the sauerkraut tasted strange last time, thought it tasted better with the dressing.

And so the first new product was finally completed.

Encouraged by this experience, Liu Nanjia continued to research fried chicken sauce.

Just like the most popular ones in the past, there's a sweet and spicy sauce and a sweet and sour sauce.

And her taste testers, who started with three, gradually decreased to just Song Chen.

"No, you can't leave. You're my biggest help in doing business. Sirou can't eat spicy food. My tongue can't tell the difference anymore. You can't end up like my brother!"

Liu Nanjia grabbed Song Chen's sleeve tightly and shouted.

During this period of tasting, Liu Yanxi was actually the first to run away. He simply couldn't stand the double attack from the students and the younger sister, and he really couldn't tell the difference anymore.

Liu Sirou wanted to persevere, but she found the sweet and sour flavors delicious. As for the spicy ones, she would have to drink a whole vat of water after each bite, and she would forget what they tasted like long afterward.

Liu Nanjia couldn't bear to torment her any longer, so she let her go.

So only Song Chen was left, which led to the scene just now.
