It's impossible to have a well-stocked bar without orange liqueur, also known as curaçao or triple sec. It would be quicker to list cocktails that don't contain orange liqueur than to list the ones that do. Top-shelf brands like Grand Marnier and Cointreau are a little pricey, while the bottom-shelf options can drag a good drink into the gutter fast. But homemade orange liqueur is just right...and it's a blast to make.

Notes: Dried bitter orange peels are available at homebrew shops or herb specialists, but you can also order them online. If you're feeling like playing mad scientist, try new herb or spice combinations like adding cinnamon or vanilla. Your homemade orange liqueur does not need to be refrigerated. It can last for a year, but is best when used within a few months.
