We refer “sauce” (pronounced So-su in Japanese) as a thicker version of Worcestershire sauce. So-su (ソース) comes in three types: thin, medium-thick, and extra thick.
- Thin sauce – Usutah So-su (ウスターソース) similar to Worcestershire sauce but a bit sweeter.
- Medium-thick sauce – Chuno So-su (中濃ソース)
- Thick sauce – Tonkatsu So-su (とんかつソース) which is used for dishes like Tonkatsu. The major sauce brand in Japan is called Bulldog (see the picture above).
