Lime

The Indian lime, which originated in Malaysia, is the archetype of the citrus family, its acidity and taste familiar to those who savor Key limes from Florida. It is small, its skin is thin, and its acidity is quite strong. These limes are pickled in assertive spices and breathe their tart, fiery-hot breath when served alongside many of our curries. The lime juice provides a clean, crisp tartness and is usually stirred in after the curry has cooked, just before serving. When limes are called for in my recipes, regular ones work perfectly well, but if Key limes are available, give them a try.
