Taste and looks of the 5to7 fresh mango soufflé

The 5to7 fresh mango soufflé has white cream wrapped around a fluffy soufflé with yellow mango sorbet in the middle, so it looks like a fried egg. After a short wait, it came out with the drinks on a big wooden tray!!

The first thing I noticed was the puffed-up soufflé T_T It looked pretty from every angle, enough that I never got tired of taking photos~

I shot it on the windowsill, and with natural light and the green scenery the photos turned out even more atmospheric! I could see right away why people looking for a Seoulsup café soufflé recommend it as a photo spot.

When I carefully cut into the soufflé, the inside was fluffy like a cloud~ The fork went in softly with barely any pressure, it was moist, and it melted in my mouth.

The sweet cream and fluffy pancake went well together, and the fresh juice of the mango kept it from feeling heavy at all~ The mango was well ripened, deeply sweet and juicy, and eating it with the soufflé made it even better.

Do the café latte and Dutch americano go with the soufflé?

The 5to7 café latte balanced the softness of milk with the rich flavor of espresso. The layers were nicely separated, so it looked pretty in photos, and stirred well it tasted nutty with a gentle sweetness~

The 5to7 Dutch americano was clean without too much acidity, so it paired well with the sweet soufflé! Sipping the americano between bites refreshed my mouth, so I enjoyed it to the very end.
