From an article about maple syrup in the Washington Post. Said it went particularly well with grilled pork tenderloin.
Ingredients
2 tablespoons grapeseed or canola oil
1/2 medium onion, finely chopped (about 1/2 cup)
2 canned chipotles in adobo, drained and chopped
1/2 cup pure maple syrup
1 cup bottled chili sauce, such as Heinz brand
1 cup no-salt-added chicken broth (may substitute vegetable broth)
Instructions
Heat the oil in a medium saucepan over medium heat. Stir in the onion and chiles; cook for about 5 minutes, until the onion begins to soften, then add the maple syrup, chili sauce and broth. Once the mixture begins to bubble, reduce the heat to medium-low and cook for about 30 minutes, or until thickened a bit.Let cool before serving or storing.
