Procedure
Assemble your immersion circulator, setting the water to 160℉.
Put all the ingredients in a heavy-duty zip-top freezer bag and seal, removing as much air as possible.
When the bath hits 160℉, add the bag and cook for 1 hour.
When the cook time is almost up, fill a large bowl with ice and water. Carefully extract the bag from the bath and submerge it in the ice bath to cool for 10 minutes.
Once cool, strain the liqueur and store in a glass jar in the refrigerator for up to 6 months.
