Place all the ingredients in a high speed blender (but only half the almond milk at this stage).
Pulse to combine, scraping down the sides to ensure all the ingredients are incorporated.
Blend on a high setting for a couple of minutes, check the consistency and add additional almond milk, enough to create a thick mousse-like consistency, in between pulses.
Taste, re-season if required; salt, apple cider vinegar or more lemon.
