Try it at 1.5oz 100 Proof Bourbon, .75oz Apricot Brandy, .75oz Suze, .5oz lemon juice.
Follow-up - the quality of the Apricot Brandy definitely matters here. The first run I made used Giffard Apricot Brandy and it was delightful. I skimped on my second batch and got a $12 bottle of lower quality brandy and it threw the balance way more in the Suze direction. Use quality ingredients for this one.
