Dubu or Tofu?

They are same thing. It is the name of our humble yet glorious food.
Dubu is how tofu is called in Korea. Firm or silken, it is essential part of Korean diet.

It is very versatile food. It can take whatever you though at it. It is up to you.
You can be bad (fried dubu cake)

or

you can be very good (Soondubu Jjigea silken dubu pot stew).

Either way, dubu never fails you. At least, it has never failed me.

Firm dubu that stewed with small bits of meat or dried anchovy is my comfort food.
