Lemon Cashew Nut Mayonnaise

An easy mayonnaise which is not only better tasting than the supermarket versions, it contains no sugar or processed oils. As all the ingredients are natural it won’t keep as long (5 days in the fridge, but you won’t find it hanging around that long anyway!)


  • 200g cashew nuts – pre-soaked for 4-8 hours
  • 100-125ml unsweetened almond milk
  • ¼ lemon, zest & juice
  • 1 tsp Dijon mustard
  • Pinch salt
  • 1 tbsp apple cider vinegar


  • 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.


This mayonnaise accompanies beautifully the Pea Burger. It will keep in an airtight container in the fridge for 5 days. Experiment using different herbs and spices to create flavoured mayonnaise.
Caution: fresh basil and mint leaves bruise easily and may turn black, giving an unappealing look to the condiment.
