How can I get more lime flavor into my key lime cake recipe?
My daughter who loves lemon cake thought of a great idea a couple years ago to knock the lemon flavor out of the park. I'm sure it would work for lime too: make a lime syrup and pour it into the bottom of the cake after poking it all over with a thin skewer. The more lime you like, the more syrup you use. As a bonus, it also adds some moisture to the cake.  Note that you may need to refrigerate the cake after this step (if it lasts more than a few hours).
