Description

Tonkatsu sauce (とんかつソース) is Japan's interpretation of Worcestershire sauce — thicker, sweeter, more complex, used specifically for tonkatsu (breaded pork cutlet) and other yoshoku dishes. The original: Bull-Dog brand (founded 1902) with fruit purées (apple, tomato, prune), vegetables, vinegar, sugar, and spices — a considerably different product from Lea & Perrins Worcestershire. Multiple grades: regular tonkatsu sauce, chu-noh (medium thick, for yakisoba), and tonkatsu sauce (thick). Japanese consumers use these sauces with extreme specificity. Home production: combine ketchup + Worcestershire + mirin + mustard for approximate version.
