Kaffir lime leaf adds an unmistakable, refereshing taste that is essential in many Thai soups & curries. The combination of lemongrass and lime leaf is a fantastic blast of flavor. The leaves have a strong fragrance and flavor that can not really be substituted. To experience the wonderful aroma, sliver the leaves with a knife or scissors and you'll begin to understand just how wonderful this plant is. Kaffir lime leaves grow in doubles. Sizes vary, but the average individual leaf is approx 2" long. Harvesting is done by hand and it's difficult because the branches have long thorns, so they tend to be expensive and not easily found in supermarkets. They freeze very well-just place in a ziplock bag & they'll retain their flavor for months.
