Mayonnaise

Egg yolks, oil, mustard. The universal binder — everything else in this list starts here.

Mayonnaise

Debate rages about whether the sauce comes from Mahón in Menorca or from a French chef's improvisation in the 1750s. Doesn't matter. What matters: made properly, from scratch, mayonnaise is a revelation. Shop-bought is a compromise the French will never forgive you for.

Method

  1. 01

    Bring 2 egg yolks to room temperature — cold yolks refuse to emulsify. Whisk with 1 tsp Dijon and a pinch of salt.

  2. 02

    Add 250ml neutral oil (sunflower, grapeseed) DROP BY DROP at first, whisking hard. After the first two tablespoons, thicken up and pour in a thin, steady stream.

  3. 03

    Once you have a thick, pale, glossy mayonnaise, whisk in 1 tbsp white wine vinegar or lemon juice. Taste and adjust salt.

  4. 04

    For the modern robot version: same ingredients into a jug blender, blitz until thick. Takes twenty seconds and works every time.

Chef's notebook
  • “The oil matters. Extra virgin will overpower — use half neutral, half olive oil at most.”
  • “If it splits: start a new yolk in a clean bowl, drizzle the split sauce back in slowly. Rescued.”
