Lemongrass
Lemongrass is a favorite in the culinary world (especially Southeast Asia). It has a mixture of lemon and mint taste, yet it is very light, so none of the flavors will overpower. It is why it is so popular in not only foods but in gins. It is easy to add in subtle flavors without going over the top. It also brings the taste of lemon without the bitterness that often comes with the citrus plant.
