Does anyone have a nice whisky liqueur recipe?

I have decided to make my own alcohols out of vodka, I have made some nice white sambuca by infusing with anise, peppermint snaps and a few others.

Now I want to try whiskey liqueur. My first go did not taste nice, I tried 300mL Canadian Club, with a cinnamon stick, 1/2 vanilla pod, 10 coriander seeds, clove, nob of ginger and cardamom pod, left for three weeks, then added melted honey.

The consistency was fine, but something I added over powered it, I think it was the cinnamon. On to my second try now.

Has anyone else perfected a recipe out there? What are everyone’s tips?

There is no bad answer! All comments welcome
