In a small saucepan, stir together honey, lemon juice, and water. Once the honey has dissolved, turn on your burner to medium heat. Next, take your stem of mint leaves and lightly bruise the leaves by tapping them with the back of a knife of spoon. Add it into the saucepan with your honey and water mixture. Stir for 2 minutes or so until you start smelling the mint. Remove the sauce pan and allow to cool on the counter. If you're in a hurry you can also stick the syrup into the freezer.
