DIY Orange Bitters
Just a drop or two of orange bitters can add the right depth to your cocktail or bridge together ingredients that aren't quite living up to their mixological potential. Deep, citrusy, spicy, complex orange bitters are an essential part of so many balanced cocktails. The beauty of DIY bitters is unleashing your creativity and crafting bitters that you can't find anywhere else. I emphasized anise, but you could just as easily play up the cloves or add cardamom, cinnamon, coriander, or ginger for a whole new flavor profile.
Gentian root and quassia chips can usually be found at specialty herb stores. You can also order them from Lhasa Karnak.
I used Wild Turkey 101 and Everclear 151 for my spirits base. If you cannot find these, you can substitute another bourbon and use the highest proof vodka available to you. Many stores sell dried orange peels, so you have the option of store-bought instead of drying your own. I used navel oranges, but you can try different types of oranges.
