Mos Burger's popular series "Extraordinary Hamburger Sandwich". Focusing on domestic ingredients, volume, and seasonality, it has sold a total of about 89 million meals since its launch in 2008. The autumn limited flavor "Demi-glace sauce with aligot" will be released on September 3rd.

This time, the eating editorial department infiltrated the kitchen of Mos Burger headquarters. We asked him about his commitment to the new product, "Extraordinary Hamburger Sandwich with Demi-glace Sauce with Aligot"!
◆ Commitment to materials

The first thing I saw in the kitchen was the hamburger steak before it was baked. The point of the "Tobikiri Hamburger Sandwich" series is the patty, which is about 1.5 times more than usual, using domestically produced minced beef and pork. By using minced meat that is familiar in Japan, it has a juicy and soft texture.
Arrange this hamburger on an iron plate and set a timer. Along with the sizzling sound, the oil is lumpy and the smell looks delicious. Yeah, it's messy ...! While watching the timer, turn it over several times and bake it. This timer is just a guide, and it seems that the timing of turning over and the baking are at the discretion of the person who cooks. There is a little trick to turning it over so that it doesn't burn on the iron plate.
While baking the hamburger, toast the buns with a special toaster. Lightly bake the surface. The buns, which have a fluffy texture and a slight sweetness, are finished in a "Japanese taste" taste, and are a gentle taste that you will want to sell by themselves.
Next, we will warm up "Aligo" and "Demi-glace sauce", which are also the main characters of this time.

Aligot is a French regional dish like mashed potatoes. At Mos Burger, a generous amount of mozzarella cheese is added to potatoes produced in Hokkaido to create an original aligot with a rich cheese scent. Before warming, it looks like a bitter potato, but when heat is applied, the cheese melts and becomes smooth. Garlic and black pepper are also added to give it a punchy taste.
In addition, the demiglace sauce is made with wine and sherry to add depth to the taste, giving it an "adult taste" with a modest sweetness.

Sandwich these hamburger patties, aligo, demiglace sauce, and onion slices with buns to complete the "excellent hamburger sandwich with demiglace sauce with aligot".

◆ We are particular about "balance" of material

Not to mention the taste of the ingredients themselves, Mos Burger's most important thing is the "balance when the ingredients are combined into a hamburger."

For example, if you eat only demiglace sauce, you can feel the richness, but the taste is strong, and it is not a taste that you can enjoy while tasting. However, when combined with hamburger patty and aligot, the richness of the sauce is enhanced, and at the same time, the taste of each ingredient is enhanced. You can see the commitment to product development.

Speaking of Mos Burger, the taste of freshly made Mos Burger is also attractive after receiving an order. The buns and hamburgers are freshly baked, and the sauce must be heated at the store before use, so you can enjoy it as if you were eating a "hamburger plate" at a restaurant.
The "Extraordinary Hamburger Sandwich" series, which is made from domestic materials and handmade at stores, as if the "hamburger plate" was made into a single hamburger. When eating, I think it's delicious so that you don't forget the efforts and commitment of the people involved in product development and the staff who make it at the store!
