How to Make It
In a medium saucepan, combine the dates and half of the root beer. Bring to a simmer and cook over moderately low heat, stirring occasionally, until the dates are very soft, about 40 minutes. Add water by the tablespoon if the dates get too dry before they’re soft.
Transfer the date mixture to a blender, add the remaining root beer and puree until smooth. Season with salt.
Roasted pork, lamb or duck or broiled or grilled salmon or mackerel.
