Rhubarb BBQ Sauce

Servings: Makes About 2 1/2 cups
Prep Time: 40 minutes
Cook Time: 45 minutes

Ingredients:

1 lb. rhubarb, trimmed and chopped (about 2 cups)

3/4 cup plus 1 Tbsp. sugar

Salt

2 Tbsp. vegetable oil

1 cup finely chopped onion

1 garlic clove, minced

1 tsp. chili powder

1/4 tsp. cayenne pepper

1 cup ketchup

1/3 cup mild molasses

2 Tbsp. Worcestershire sauce

1 Tbsp. plus 2 tsp. apple cider vinegar

1 Tbsp. Dijon mustard

 

 

1. Combine rhubarb, sugar, and a pinch of salt in a medium saucepan and let sit until rhubarb has softened and released some of its liquid, about 30 minutes, stirring occasionally.

2. Bring mixture to a boil over medium heat and cook, stirring occasionally, until rhubarb is broken down, 6 to 8 minutes. Let cool slightly, then transfer to a blender and puree until nearly smooth, 30 to 60 seconds; set aside.

3. Rinse saucepan, then add oil and heat over medium heat until shimmering. Add onion and cook, stirring occasionally, until softened and golden brown, 5 to 7 minutes.

4. Add garlic, chili powder, and cayenne and cook, stirring constantly, 30 seconds. Add rhubarb puree, ketchup, molasses, Worcestershire sauce, 1 tablespoon vinegar, and the mustard and stir to combine. Return to a simmer and cook, stirring occasionally, until mixture is thick and reduced to about 2 1/2 cups, 25 to 30 minutes, adjusting heat as necessary to maintain a medium simmer.

5. Remove from heat and stir in remaining 2 teaspoons vinegar and 1/2 teaspoon salt; let cool to room temperature. Refrigerate in an airtight container for up to two weeks.
