We buy tofu at one of the Korean supermarkets (H-Mart or Lotte).
I'm half-Japanese and love my Japanese tofu cold and plain with a drizzle of soy sauce or vinaigrette, like they serve in restaurants. The finest it is, the better (soft tofu, not firm or grainy).
My husband is Vietnamese and hates the above tofu recipe. He take firm tofu and fries it in slices, then dips it into an awful thick non-Japanese soy sauce. I hate it.
This is our only food incompatibility
