While not a primary ingredient, zest, particularly lemon and lime zest, is used in some modern and fusion Indian recipes to add a bright, citrusy flavor. It's not a traditional element in most classic dishes.
Traditional Indian cooking relies heavily on a complex blend of spices, herbs, and aromatics like ginger, garlic, chilies, and various spice powders. Citrus flavors are typically introduced through the use of juice, such as lemon or lime juice, or through souring agents like amchur (dried mango powder) or kokum. Zest, which is the outer colored part of citrus fruit, contains concentrated citrus oils that provide a potent aroma and flavor. While not a staple in ancient recipes, the use of zest has found its way into contemporary Indian cuisine, especially in desserts, marinades, and fusion dishes where chefs are experimenting with new flavor combinations. The zest adds a refreshing top note that complements the richness of traditional Indian spices.
When using zest in Indian cooking, be sure to use organic citrus fruits and wash them thoroughly before zesting to remove any potential pesticides or waxes. Only zest the colored part of the peel, avoiding the white pith underneath, as it can be bitter.
