What can I substitute for Kaffir Lime Leaves?
I wouldn't attempt to substitute. I've read somewhere that you can use regular lime leaves, but I've never seen those anywhere. Even Googling for lime leaf turns up kaffir lime leaves.

They can be found easily enough online: ImportFood.com. They freeze well for months in just a zip-lock bag.

The flavor profile is best described as a bright floral aromatic. It's similar in function, not taste, to a bay leaf. Thai cuisine uses kaffir lime leaves much as we do bay leaves.



If you decide buying online isn't worth the hassle, then Kitchen Savvy suggests the following substitute:


1/2 a small bay leaf
1/4 tsp of lime zest
1/8 tsp of fresh lemon thyme
