Add all of the ingredients to a high powered blender or food processor and blend until well combined. An immersion blender will also work.
Season with salt and pepper to taste (just a little at a time), then blend again and taste. Add more salt and pepper, if necessary. Store the sauce in the fridge in an airtight container and give it a good stir before serving. It will keep and stay fresh for upwards of 3 to 4 days.
