I was reading Where the Red Fern Grows aloud. I got to this section:
and one of the kids said, "What is horehound?"
I said, "I assume from the context that it's some kind of old fashioned candy. Never heard of it." I looked it up and discovered it's a plant. I thought it would make a yucky licorice-tasting candy. But in the interest of education, I bought some. (Surprisingly easy to find and cheap).
It was actually good, and we all liked it!
