How to substitute mayonnaise, step by step

  1. 1

    Pick the right substitute for the job

    For most recipes use Aquafaba mayo — homemade, cheap, neutral. If you need a different texture, Soy milk + oil immersion-blended mayo works for 1-minute homemade.

  2. 2

    Measure using the correct ratio

    1:1. Weigh rather than eyeball it — small errors show up much faster when replacing mayonnaise.

  3. 3

    Adjust the method

    Blend soy milk and oil with the stick blender held still for 10 seconds before lifting — that's what makes it emulsify.

  4. 4

    Taste and correct

    Plant swaps are usually a little less salty and less rich than mayonnaise. Season at the end and add acid (lemon, vinegar) or umami (miso, nutritional yeast) if the dish tastes flat.

Mistakes to avoid

  • Swapping by volume when the recipe measures mayonnaise by weight — check the ratio above first.
  • Using a sweetened or flavoured version in a savoury recipe.
  • Ignoring the method change: Blend soy milk and oil with the stick blender held still for 10 seconds before lifting — that's what makes it emulsify.
  • Assuming every packaged product labelled "plant-based" is vegan — some still contain milk powder, honey or egg. Scan the barcode to be sure.
