Eggnog is the official beverage of December. It's rare to encounter it any other time, and truly is Christmas spirit in a cup. Here's a vegan version based on cashews and dates.
Combine all ingredients in a blender (including the water you soaked the dates in) and blend until smooth and frothy. This can take a few minutes in an older blender.
Transfer to a container and chill in the refrigerator until needed.
When ready to serve, place back into blender to allow more frothing because mixture can separate. Pour into mugs and garnish with fresh grated nutmeg.
