Homemade Tonkatsu Sauce

You can buy this sauce ready made in most Asian shops, but if you feel like making it yourself, this is a great one to have ready in the fridge. I always like to know what’s in my food, and making it yourself means you can adjust it to suit your own taste. The sauce is made from stewed fruit and vegetables simmered in soy, sugar and vinegar. The same sauce is used for takoyaki, okonomiyaki, tonkatsu, kushi katsu and many other dishes. It keeps a long time, like many of the bases in this book. For kushi katsu you need to add a bit more soy sauce and Worcestershire to this base.
