How to prepare Stevia leaves for consumption?
Stevia leaves are commonly cut, then hung for drying, then either ground up into little flakes and used sparingly in drinks such as teas or recipes. The leaves themselves are also very commonly used unground as garnish in drinks as well as added to recipes.

Just remember to compensate accordingly for the extra sweetness they will provide, and you really cant go wrong with some experimentation at first.

In terms of a particular recipe I'm not really sure what to recommend so hopefully this is still helpful.
