Mayonnaise is a thick emulsion of oil, egg yolk, and an acid such as vinegar or lemon juice. One metric cup (250 ml) weighs around 230 grams or 8.11 ounces. Most cooks reach for it as a sandwich spread or salad dressing base, but it also keeps cakes and quick breads moist when used in place of oil or sour cream.

Jars of mayonnaise are sold by volume in millilitres or by weight in grams, while recipes mix cups, tablespoons, and grams. Converting between the three saves you over-spooning into a chocolate cake batter that calls for half a cup.

  • mayo
  • real mayonnaise

Sour cream is tangier and slightly heavier than mayonnaise (250 g vs 230 g per cup). They swap 1:1 in dressings, slaws, and dips, with mayonnaise giving a richer, less tangy result. In cake batters that lean on sour cream for tenderness, mayonnaise is a workable stand-in since both are mostly fat and water. See what 1 US cup of sour cream is in teaspoons.
