A vibrant green pesto perfect for spreading onto crusty bread and serving with soup
Put all of the ingredients into the blender jug in the order they're listed and blitz on full speed. You may need to push the watercress down with a stamper.
Pour into a clean jam jar, seal with a lid and store in the fridge until needed. Ideal for spreading on crusty bread/toast, stirring through pasta, spooning onto fish or just as a dip.
