  • food processor or immersion blender


  • 2 egg yolks room temperature
  • 1 tsp dijon mustard heaped
  • 1 tbsp apple cider vinegar or white wine vinegar, up to 1.5 tbsp
  • 1 ½ cups / 300 ml light tasting olive oil, macadamia, light walnut or avocado oil (I used 1 cup light olive oil and ¼ cup extra virgin olive oil)
  • 1 tbsp lemon juice or 2 tbsp, to taste
  • ¼ tsp salt or to taste
  • cracked black pepper optional


  • Place the egg yolks, dijon mustard and apple cider vinegar in the small bowl of a food processor.
  • Start the food processor and very slowly drizzle in the oil whilst the S blade is running. TAKE YOUR TIME WITH THIS!!!!! Keep gradually pouring in the oil until the mayonnaise reaches a nice thick consistency.
  • Once thick, add the lemon juice and salt and blitz again for a few seconds to combine.


I used a Magimix food processor, but any food processor with a small bowl works.
Makes approx. 1.5 cups.
Serves 12 (2 tbsp per serve)

Extra virgin olive oil is delicious but quite strong for mayonnaise. You may like to mix it with another of the oils mentioned above.
If you find that your mayonnaise ends up too thick you can add a few drops of water and stir through with a spatula.
Storage: Fridge in a sealed glass jar for up to 2 weeks.
