Tonkatsu sauce

Tonkatsu sauce is Japanese sauce that used for tonkatsu which is Japanese style fried breaded pork cutlets and for other fried foods mainly.  The taste is somewhere between Worcestershire sauce and barbecue sauce, and it has very distinctive flavor. I always though it would be nice to be able make my own, but this is like Worcestershire sauce that it is almost impossible to recreate at home since there are so many different ingredients including spices.  

The most people just combine ketchup, Worcestershire sauce, soy sauce, sugar, and maybe oyster sauce.  I think it works, but I really wanted to make my own. So what I did was to start with V8 juice, and added other ingredients that I though might go with.  It came out pretty good, I think. You would probably like it unless you are not the type of person who only accept the paricular brand of tonkatsu sauce from a store which is typical.

Ingredients:
V8 (5.5 oz) juice
1/2 apple, peeled and grated
1/4 onion, grated
1 garlic, grated
1″ ginger, grated
4 Tablespoon ketchup
4 tablespoon Worcestershire
2 tablespoon soy sauce
1 tablespoon oyster sauce
1 tablespoon sugar
1 tablespoon apple cider vinegar

Preparations:
Add V8, apple, onion, garlic and ginger in a small sauce pan, and simmer for about 10 minutes until slightly thickens.  Add the rest of ingredients and cook for another 5 minutes. Adjust the seasoning with sugar and vinegar. Let it cool, and store in a jar.  Keep it in the fridge for a few weeks.
