I have taken the top leaves of the fennel bulb (called anise) and made sucking candy with them. It is quite simple

1 cup of sugar
1/4 cup of water
boil until 239 degrees (use a candy themometer)
add 3T of anise leaves

pour onto sheet pan and let it sit till it becomes hard. Break into pieces and suck one piece at a time. It has a very nice licorice flavor. You can add food coloring to make it look pretty. But they are beginning to link food color to autism so on second thought forget the food coloring unless you already have autism
