Combine all ingredients in the pitcher of a blender.
Blend for a few minutes until as smooth as possible. Adjust seasoning if needed.
Pour into a mesh strainer over a bowl, hitting the strainer against the heel of your hand to get the sauce to pass through. For the best texture, do not force the last 1/4 cup or so through - use it as a spread or eat it right now with a spoon.
Store sauce in a squeeze bottle or small glass bottle in refrigerator.
