Japanese Ebi Fry with Tonkatsu Sauce

This panko fried shrimp is very popular on Japanese menus and so easy to make at home.  The shrimp is dusted in flour, then egg, then panko bread crumbs and fried for about 90 seconds on each side.  The tonkatsu sauce is a simple mixture of melted butter, ketchup, worcestershire sauce, soy sauce and a sprinkling of sugar.  Mix in a saucepan and heat through then chill before serving.
