Orange Bitters

Just started a batch of orange bitters I found on Time magazine's blog. Added a star anise pod and kept my orange peel long for the look. Used a 100 proof vodka and will be waiting 14 days for this to get ready. Excited to have my own. A Martinez has become one of me favorite cocktails, and I can use my own bitters when I'm done.
