Tonkatsu sauce or katsu sauce is a Japanese sauce served with tonkatsu (pork cutlet). It is a thick (viscosity over 2.0 pascal-second, per JAS Standard) Japanese Worcestershire-type sauce. It is similar to a brown sauce (British Isles), and can include a fish sauce, tomatoes, prunes, dates, apples, lemon juice, carrots, onions, and celery among its ingredients.[1][2]

History and varieties

The first tonkatsu sauce was made in 1948 by Oliver Sauce Co., Ltd. of Hyogo Prefecture. The Bull-Dog brand of tonkatsu sauce, for example, is made from malt vinegar, yeast, and vegetable and fruit purees, pastes, and extracts. [3] In the United States, Kikkoman brand sells a fruity tonkatsu sauce with applesauce as the main ingredient.[4]
