Melt butter in a small skillet over medium heat. Add onion, garlic, and minced chipotle pepper; sauté 3 minutes. Stir in chicken broth, Strawberry-Lemonade Jam, orange juice, vinegar, and salt. Bring mixture to a boil, and cook, stirring occasionally, 8 minutes or until liquid is thick and syrupy. Process mixture in a blender until smooth. Cool 10 minutes.
