Related to Lemon
Lime
Lime is sharper and more floral than lemon. Persian limes (67 g) are usually smaller than a medium lemon (115 g), so two limes are usually what you need to match one lemon for juice. Lime is a good straight substitute in dressings, marinades, and cocktails. In baking, you can use lime as a substitute but expect a more lime-like flavour. See our Lime converter.
Grapefruit
Grapefruit juice swaps in cup for cup and brings tart citrus acid with a bitter, floral edge lemon lacks. For dressings, cocktails, and marinades this is a good straight swap. Expect a more complex, slightly less sharp result; reduce any added sugar slightly to account for the natural sweetness grapefruit carries. See our Grapefruit converter.
Orange
Marmalade and citrus salads often pair orange and lemon. An orange is about 190 g per cup of chopped flesh against a lemon's 220 g. See our Orange converter.
Lemon Juice
Once the fruit is squeezed the question changes: a medium lemon gives about 52 ml, so a recipe asking for a cup of juice wants roughly five of them. The lemon juice converter handles the volume and weight side of that. See our Lemon Juice converter.
Lime Juice
Cocktails and marinades often take whichever of lemon or lime is on hand. For that use swapping 1:1 by volume works. Lime is a touch more acidic, which matters if you are using it to activate baking soda rather than adding flavour or brightness. Its converter works in millilitres, cups or grams.
