Cherry Barbecue Sauce

Summer is officially here and that means it's time to start grilling! Everyone needs a go-to barbecue sauce in their life and if you are still clinging on to that bottle of Masterpiece or Sweet Baby Ray's (not that they aren't great in a pinch!) then it is time to let go and branch out - make your own! It's easier than you think. I promise. 
Cherry Barbecue Sauce  makes 1 pint

Ingredients  1 yellow onion, chopped
2 tsp grape seed oil 
3 garlic cloves, minced
2 cups dark sweet cherries*, pitted and coarsely chopped 1 cup ketchup
2/3 cup packed dark brown sugar
1/4 cup cider vinegar
1 Tbsp Worcestershire sauce
2 tsp dijon mustard 1/2 tsp chipotle pepper in adobo sauce (canned)
1/2 teaspoon pepper
1/8 teaspoon liquid smoke kosher salt, to taste 
*You can use frozen bagged cherries too if you can't find fresh
Method 1. Heat oil. Saute onion for 3-5 minutes until translucent. Add garlic. Saute until fragrant (about 1 minute) 2. Add the rest of the ingredients. Simmer for 15-20 minutes.  3. Season to taste.  4. Puree with immersion blender or actual blender. 5. Stores in fridge for 2 weeks or you can freeze until ready to use
Note: Feel free to play around with different mustards, fruits, spices, vinegars and peppers until you nail a "signature" combination. If you like asian barbecue sauces, add orange juice, hoisin, and fish sauce. Instead of chipotle peppers you can add chili flake or sriracha. Options are endless. Have fun with it.
