What to use instead of lemon

  • Lime

    Produce swap

    1 lemon = 1 to 2 limes (matched by juice volume)

    Lime is sharper and more floral than lemon. Persian limes (67 g) are smaller than a medium lemon (115 g), so two limes usually match one lemon for juice. Works in dressings, marinades, and cocktails; reduces sugar by a touch in baking to balance the extra acid.

  • Grapefruit

    Produce swap

    1 cup lemon juice = 1 cup grapefruit juice (1:1 by volume)

    Grapefruit juice sits at the same 240 g/cup and brings tart citrus acid with a bitter, floral edge lemon lacks. Works in dressings, cocktails, and marinades. Expect a more complex, slightly less sharp result; reduce any added sugar slightly to account for the natural sweetness grapefruit juice carries.
