Felicity's perfect mayonnaise

  • 2 egg yolks
  • Generous pinch of salt
  • 250ml groundnut oil (or sunflower oil)
  • 25ml extra-virgin olive, walnut or rapeseed oil
  • 1 tbs mustard of your choice (or 1 tsp mustard powder)
  • 1 clove garlic, crushed (optional)
  • 1 tbs vinegar or lemon juice

Make sure all the ingredients are at room temperature before starting. Place a damp tea towel beneath a large mixing bowl, and add the egg yolks. Beat well with a whisk for a couple of minutes.

Add the salt and beat well for 30 seconds until the yolk is thick and sticky. Begin to pour in the neutral oil in a very thin stream, or drop by drop if you're the nervous type, beating all the while don't be tempted to rush this, or your mayonnaise will split. As the mixture thickens, you can start to add it more quickly.

Once your mayonnaise is near the consistency you want it (and you may not need to use all the oil), switch to the olive oil. Once it is incorporated, beat the mayonnaise for another 30 seconds until thick and glossy. Add the acid, mustard and garlic (if using) and mix in. If you would prefer a thinner mixture, add a little water as well.

Stir in any further ingredients, such as chopped herbs or anchovy essence. Cover and keep it refrigerated. Remove just before serving.
