I was not able to make this one myself because there are a few things in the one from judy that i can not use myself. I do know that prunes (or plumbs) are in the original hp sauce, as is tamarind paste.
Am sort of back again on and off and hope you are all keeping well. An update re HP Sauce. I made both this one and Stef's recipe. Both were very good but this one IMHO is the nearest to the commercial version - all I would do is reduce the amount of allspice slightly. Stef, your recipe to me an excellent BBQ sauce and we use it for marinades etc.Am now in the middle of making a version of Tomato Ketchup and will let you know how it turns out.
