The first time I bought ponzu sauce was a happy accident.
I pulled down what I thought was a bottle of Japanese soy sauce from a high shelf at the Asian grocery. I tossed it into my shopping cart, and not until I reached the checkout line, with my cart full and my wallet in hand, did I realize I had ponzu instead of soy sauce.
I checked the ingredient list on the bottle. Well, I thought, why not give it a try?
Thus began my love affair with ponzu. Think of it "soy sauce plus", as soy is the main ingredient, but it's the combination of sweet and fruit that makes ponzu sauce a perfect base for building a glaze, or a stir-fry or barbecue sauce.
It's easy to make your own from ingredients you probably already have in the pantry, but it's easier to keep a bottle of store-bought ponzu in the refrigerator.
