The second kaffir lime leaves substitute option is Kaffir Lime leaves powder. I bought it from a spice shelf in a normal supermarket. In my opinion, the smell is much lighter than dried or frozen whole leaves, and it is quite expensive.

Another substitution option is Yuzu skin. But to be honest, I am not sure which one is more difficult to find. I never find Yuzu skin in my area so no comment here.
