A Bit of History:
After living in South Carolina for 14 years, I finally realized how deficient my knowledge surrounding BBQ sauce is. While hotly debated, most BBQ experts and websites recognize at least six main types of regional BBQ sauces. South Carolina proudly crafts four of these main sauce styles throughout the state; mustard, light tomato, heavy tomato, and vinegar/pepper. Unlike other regions, mustard based BBQ sauce appears to be unique to South Carolina. In order to pay homage to the wonderful traditions of my adopted state, I decided to try my hand at a Harissa Mustard BBQ Sauce.
BBQ sauce boasts a long history in the United States, dating back to colonial times. Most historians agree that the mustard style BBQ sauce, originated with German immigrants. Between 1730-1750, the South Carolina colony sought German immigrants to settle parts of the state, even giving the families land grants. Luckily for us, the German families brought their traditional mustard and introduced it to the colonies. Over time, a wonderful mustard base BBQ sauce developed in the region of South Carolina between Columbia and Charleston and is the inspiration for this dish.
About the Recipe: Harissa Mustard BBQ Sauce
I truly enjoy the spiciness of smoked chilies, especially in a harissa style spice rub. Harissa originated in Tunisia and features in many North African and Mediterranean dishes. Crafting harissa requires chili peppers ranging in heat level. Unfortunately, I did not have access to any peppers native to North Africa. However, I did have a large number of dried chilies on hand frequently used in Mexican cuisine. Using these fabulous peppers, I crafted a homemade harissa spice rub in just a few minutes. If you don’t have dried chilies, dried harissa powder is widely available in grocery and specialty stores and is crucial for crafting this fabulous sauce.
