I made cough drops last night that work! Even my DH got up in the night and went and go some more.
1 cup sugar
1/3 cup honey
1/3 cup water
cook until it reaches hard crack stage 310 degrees.
Add about 1/2 tablespoon of thieves oil stir and pour onto greased cookie sheet. If you have candy molds you could use them. I didn't. When it cools break it into small pieces. It was amazing. Taste? Well it IS a could drop not candy!
You can make hard candy using this, I cut the recipe in half to do the cough drops. Just add what ever flavor you want at the end.
