Cherry Chipotle BBQ Glaze

adapted by There's Always Thyme to Cook

2 tablespoons unsalted butter
1 medium onion, finely chopped (I just sliced the onions, it'll get whizzed up when you use the stick blender or food processor)
8 ounces cherry preserves (3/4 cup) (I use a bit more!)
1/4 cup minced seeded chipotle chile in adobo sauce (I use 2 – 3 chipotle's, and leave them whole – it’ll get pureed when you put it in the processor or blender. I use an immersion stick blender)
1/4 cup ketchup
1/4 cup cider vinegar

In a small saucepan, melt the butter. Add the onion and cook over moderate heat, stirring occasionally, until softened, 5 to 6 minutes. Add the remaining ingredients and cook over moderate heat, stirring, until bubbling, about 5 minutes longer. Transfer the mixture to a food processor and process until fairly smooth. Transfer to a bowl and let cool before using. The glaze can be refrigerated for up to 2 weeks.

NOTES: Use this spicy, smoky, sweet barbecue sauce to glaze grilled meat or poultry in the last few minutes of cooking. It can also be served on the side.
