Mayonnaise: what it is, how to pick and store it

An emulsion of oil, egg yolk and vinegar or lemon juice: the base of creamy dressings, slaws and sandwich spreads.

How to pick it

Full-fat for dressings and baking; light versions have more water and starch.

How to store it

Refrigerate it after opening and keep it cold.

Out of mayonnaise? What to use instead

  • Plain Greek yogurt: The same amount. Tangier and lighter; a bit looser.
  • Egg-free (vegan) mayo: The same amount. Very close.
  • Sour cream: The same amount. Tangier and less rich.
  • Mashed avocado: The same amount. Green and fresh-tasting; browns after a few hours.
