Add the chipotle peppers, sour cream, mayonnaise, maple syrup, garlic, lime juice, and salt to a blender or food processor.
Blend until smooth and creamy, pausing as needed to scrape down the sides with a spatula to ensure everything is fully incorporated.
Taste and adjust seasoning—add more lime juice for brightness, a bit more maple syrup for sweetness, or an extra pinch of salt to balance the flavor.
Transfer the sauce to a bowl or jar. Serve immediately or optionally cover and refrigerate the sauce for at least 30 minutes before serving to let the flavors meld.
