What can I use instead of anise oil in Grandma DiLaura's panettone recipe?
My guess is that you could put a few pinches of anise seeds or fennel seeds into the dough. I say pinches, because although the seeds is small, the flavor is big.
Another alternative (suggested by the recipe itself) is anise extract (4 tsp instead of 1 tsp anise oil) as a replacement.
And if stores near you don't have that, maybe they have licorce (root) extract, which has a similar flavor.
