Lemon juice is a tart, acidic liquid used in sweet and savoury baking alike. It activates baking soda, adds brightness to glazes and icing, and balances sweetness in fruit-based recipes. One metric cup (250 ml) holds 255 g (8.99 oz).

Getting the amount right matters: too much acid can affect rise and flavour balance. Measuring by weight rather than volume gives consistent results, especially when scaling recipes up or down.

Buttermilk Substitute Calculator

White vinegar is sharper and more concentrated than lemon juice. Use roughly half the amount of white vinegar when substituting, and expect a neutral flavour without any citrus notes. See our White Vinegar converter.

Buttermilk is thicker and dairy-based, but both activate baking soda in a similar way. Stir 1 tablespoon of lemon juice into 1 cup of milk and let it sit for a few minutes to make a quick buttermilk substitute. See our Buttermilk converter.

Lime juice is sharper and more floral than lemon juice. Close in weight (248 g vs 255 g per cup), so swap 1:1 in dressings, marinades, and cocktails; expect a more aromatic finish. See our Lime Juice converter.
