Substitutes
Lemons are the most seamless lime substitute. The flavor is slightly more tart and less floral than lime, but the acidity level is identical. Use both the juice and zest interchangeably in most recipes.
Grapefruit offers citrus acidity with a bitter, complex edge. Use as a lime substitute in cocktails and dressings. The flavor is quite different but provides similar acidic brightness.
For acidic function only β use half the amount. Works in cooked dishes, dressings, and marinades where lime's acid is the key function. Lacks citrus flavor entirely.
