Mayonnaise, a simple emulsion of egg yolk and oil, is the base for many delicious sauces and dips, as well as being a great spread for sandwiches – and it’s so easy to make! Salt plus acid, in the form of lemon juice or vinegar, help preserve and flavour it. A little mustard (prepared or dried) helps the emulsification and taste too. Mayonnaise is the base recipe for aïoli, skordalia, tartare sauce, sauce Marie Rose (a.k.a. cocktail sauce or Thousand Island dressing), rémoulade, comeback sauce, Alabama white sauce, ranch dressing and many other delicious sauces and dressings. It’s best if eggs are at room temperature when making mayo; I like to use a whole egg as well as an egg yolk as it gives a lighter result and is less wasteful. Don’t worry if your mayonnaise splits (it’s more likely if the eggs are cold) as it can usually be fixed – and I’ll step you through how to do that here. Chefs usually whisk mayonnaise by hand, but I find it easiest to make using a stick blender. You can make a half-quantity of this recipe using 1 whole egg (no egg yolk) and ¾ cup oil, with half the lemon juice, mustard and salt.

Makes about 350ml

Ingredients
  • 1 egg
  • 1 egg yolk
  • 1 tablespoon strained lemon juice, or more to taste
  • 1 teaspoon mustard powder
  • ½ teaspoon salt flakes, crushed
  • 1 cup vegetable oil
Method
  1. Place egg, egg yolk, lemon juice, mustard and salt in the jug of a stick blender.
  2. Blitz to combine well.
  3. With the motor running, very slowly drizzle in the oil to form a thick emulsion.
  4. Taste and add a little more lemon juice if you like a sharper flavour.
  5. Transfer to an airtight container, cover and refrigerate.
  6. Adjust the consistency with a little water if you want it thinner for a dressing or drizzling.
  7. Store whole egg mayonnaise for up to 5 days.

We made the pot-sticker dumplings and bang bang chicken from the Chinese class the other night. Once again both exceeded our expectations. My husband keeps saying it’s better than going out to restaurants as the recipes and quality are amazing.

Thank you for stocking our pantry with such authentic Ingredients and quality produce. We really like the flexibility of cooking over a couple of days and changing the order we cook the dishes in when we want to. And I love listening to the themed playlist while cooking.

I am absolutely loving Be Inspired! There are ingredients I have never worked with before so having the confidence to try something new is so much fun! The recipes are just amazing and the notes on what can be prep’d beforehand are a great help too. Thank you so much.

Food, wine and travel! Three of my favourite things! Be Inspired with Roberta has been a wonderful experience and given me more confidence in the kitchen. I have learnt so much, cooked things I never would have attempted without Roberta’s excellent videos, and used ingredients I have never tried before.

I'm a competent cook whose learned so much from Roberta's online cooking classes. The recipes are yummy and Roberta’s video guidance offers so many little tips to improve flavour and organise the flow of preparation. I enjoy her warmth, sense of humour, and ability to giggle at herself when she occasionally messes up.
