Why buy steak sauce when you can make your own at home. And, since you are making it you can adjust the flavor to your own taste rather than what someone else thinks you like.
This home made sauce is also more economical than sauce purchased from the store. Use it as you would any store bought steak sauce.
In step 1 of the recipe, before removing from the stove, taste the sauce and adjust ingredients as needed. If you like it sweeter, add sugar. More tart...add vinegar. It is not in the recipe but if you want a little "kick" add a teaspoon of cayenne pepper.
