Yep I've done something similar, you can follow what I did here,

This is getting even better with age, and when I finish painting the house and can get back into my kitchen I plan on doing more of it.
Unfortunately I only made 11 bottles of this and the last one is in the fridge for tonight, if I remember I'll take a picture of it.
Can you post your recipe?
