I really don't like anise flavored foods, so this is definitely not a day I'll be celebrating. Anisette is anise flavor liqueur typically made in Europe. (Some sites say Italy, some say "Spanish-speaking countries," and others say France. I figure sticking with "Europe" is my best bet.)
You can make plenty of different drinks using anisette. As with all liqeuers, you can also bake cookies and cakes with anisette. Or how about Anise-Raisin Focaccia?
Of course, you can always just drink it.
