Actually, I didn’t know that either. This is an unique seasoning , born in Yame (one of the biggest tea producing areas), using Yame tea, vinegar and pepper. Tea is “cha” in Japanese, so this seasoning is named “Chabasuko”, not Tabasuco. Ha, ha.
I hear this seasoning goes well with even vanilla ice cream. Interesting, doesn’t it?
