Have all your ingredients collected? Let's get started.
Cut a flat section out of a fresh orange, slice it in half and place it in a flat bottomed, sturdy glass (that second slice will work nicely for a second drink.)
Spoon one maraschino cherry out and place it on the orange slice in the glass. I personally like Luxardo, but any will do in a pinch.
Add 3 to 4 dashes of bitters to the fruit in the glass. There are many different varieties of bitters but Angostura is a bar standard, easy to find and a great place to start.
Add 1/3 ounce of simple syrup to the fruit and bitters.
Time to muddle. The secret is not to crush it into a pulp. Give it a few good presses and twists to extract the juices and mix the concoction.
It should look like this once you're done.
Pour in 2 ounces of rye. Bulleit Rye is my go-to, but any top-shelf rye will do.
Now, add ice up to the brim of the glass. Waterford hand-cut old fashioned glass not required, but it might make you feel fancier.
Stir with a bar spoon for a few seconds. Spin the entire mixture of ice and drink in a circle without crushing the ice by facing the spoon into the center and letting it spin loosely in your hand.
You're all finished. Make a second for a good friend and enjoy!
