The foods available in Costa Rica definitely inspire experiments - if you click on the "recipe" label on the sidebar, you will see all of mine (the successful ones anyway - my Starfruit Chicken was a complete bust).
At the same time, I'm on the lookout for interesting pre-invented :) recipes. In the next year, I hope to spend some time learning some cooking from Teresita (the mother in our Orosí family) - wow! what a fabulous cook!
But until then, I just keep my eyes open for other possibilities. Here is one I just found - Platillos Latinos - it is a free ebook of heart-healthy traditional Latino recipes. And it is bilingual, so you can learn some Spanish while cooking :D.
