Peach season (or any fruit you want) is always an excuse to inject flavour and bring out the inherent subtle tastes. In this case, the whiskey will deepen the natural flavour of the peaches, as will the cinnamon, nutmeg and lemon. The guava jam adds to the sweetness (because, well, peaches are not THAT sweet, but that's okay!). They also give the turnovers a tropical flavour profile, and guavas have a unique taste and floral undertones as peaches do.

Like most recipes on this blog, you can tweak this one to your liking, but the result will be something quick and tasty.
