Squeeze lime juice into a tall cocktail glass then drop in the rinds.
Add the fresh mint then muddle.
Add ice.
Add the rum then top with Coke.
Give it a light stir.
If you need it a little sweeter, add agave syrup to taste.
Notes
I used an aged rum but typically you use a white rum. You can make the drink your own by changing things up and even trying spiced rum or some other flavored rum.
You may have heard about Mexican Coke. Grab that if you can find it. It really does taste better.
I guess you could also try it with Pepsi. But ew. I don't eff with Pepsi.
You can leave out the rum and turn this into a delicious mocktail. Lime and mint with Coke is delish!
