I found this recipe while going through my late mother Johnetta Miller's metal recipe file box. It's attributed to her mother, Roberta Solomon. Grandmother Solomon—I called her Granny— grew up in Chattanooga, Tennessee. The combination of brown sugar, mustard and vinegar gives this sauce a tangy and slightly sweet flavor. This was my family's go-to sauce to add to barbecued chicken and pork spareribs which were served "dry." For us, barbecue season was essentially the summer holidays: Memorial Day, the Fourth of July and Labor Day. This sauce pairs well with any baked or grilled chicken and pork dishes. To enhance the sauce's tanginess, a halved lemon would be added as the sauce cooked. I have fond memories of seeing that floating lemon and finding a stray lemon seed as I slathered the sauce on my barbecue.
