I also tried it at the En-eating editorial department. The price is 290 yen (tax included), which is quite bullish. But if you like "fluffy eggs", you might want to try them once.
The fluffy egg sandwich comes in a rectangular paper pack. As far as the cross section is seen, it is certainly full of ingredients and thick, and it seems to be satisfying to eat.
Compared to the previously sold "specialized egg salad sandwich" (198 yen including tax), the egg cutting method is different, but it is certainly about twice as thick.
There are two types of sandwiched eggs: omelet-style and chopped boiled eggs. According to 7-ELEVEN, the omelet-style eggs are scrambled eggs and then baked in the oven.
When I tried it, it was fluffy without betraying its appearance! The chopped egg is an accent, and you can enjoy the texture of W, which is fluffy but chewy. The general egg sandwich is sticky, and there are some that make you feel like you are eating bread and bread, but this product makes you feel that the texture of W is "a lot of ingredients".
After all the point is an omelet-style egg. It has a very fine finish, and the smooth texture like a mousse is impressive. The seasoning is also solid. Based on mayonnaise, it seems that condensed milk is added as a secret ingredient, and it has a rich richness.
On the other hand, the boiled egg has a slightly spicy mustard. But if you eat it with an omelet-style egg, you may hardly notice it. That's how rich the omelet-style egg is.
The fluffy and rich richness that was not found in the egg sandwiches at convenience stores so far was an impressive dish.
However, for the author who likes egg sandwiches that feel like "I'm eating boiled eggs!", I like the conventional version because it has a lot of egg feeling. If you pay the same 290 yen, you will probably buy the usual egg sandwich and coffee. I thought that if you had an "egg salad roll" (115 yen including tax) with eggs sandwiched in a roll, you could buy 2.5 pieces for 290 yen.
Anyway, if you are interested in "fluffy eggs", please give it a try.
