Hoisin Barbecue Sauce

Ingredients

• 1 tablespoon vegetable oil
• 1 small yellow onion, diced
• 3 medium cloves garlic, minced
• 2/3 cup hoisin sauce
• 1/2 cup ketchup
• 1/3 cup dry sherry
• 1/3 cup rice vinegar
• 1/4 cup honey
• 2 tablespoon soy sauce
• 1 tablespoon Sriracha
• 1/2 teaspoon ground Szechuan peppercorns
• 1/2 teaspoon ground white pepper
• 1/4 teaspoon Chinese five-spice powder

Directions

1. Warm the oil in a medium saucepan set over medium heat, just until it starts to glisten. Stir in the onion and cook it until tender, about 5 minutes. Add the garlic and cook briefly, just until you can smell it, about 30 seconds.
2. Stir in the hoisin sauce along with the ketchup, sherry, rice vinegar, honey, soy sauce, Sriracha, Szechuan peppercorns, white pepper, and Chinese five-spice powder. Once everything is mixed together, bring the sauce up to a boil, then turn the heat to low. Simmer, stirring now and then, until it has thickened a bit, about 15 to 20 minutes.
3. Puree the sauce until smooth with an immersion blender, or pour it into the jar of a countertop blender and blend it there. Cool it to room temperature, then spoon it into a jar and refrigerate for up to a month.
