Tonkatsu Sauce mainly consists of vegetables and fruits such as tomatoes, prunes, dates, apples, lemon juice, carrots, onions, and celery. It also includes more than 10 kinds of spices along with soy sauce, vinegar, and sugar. It’s a lot of work to make it from scratch, but you can definitely make a simplified version that tastes just as good to go with your homemade tonkatsu.
