Prep: 12 minutes, Cook: 3 hours
Slow-Cooker Size: 3- or 3 1/2-quart
Combine first 4 ingredients in a 3- or 3 1/2-quart slow cooker.
Cover and cook on LOW 3 hours or until thoroughly heated. Whisk well before serving. Serve warm with cinnamon sticks.
Lemon Squeeze: We prefer the taste of fresh lemons, but if you don't want to do all that squeezing, substitute lemon juice from concentrate.
