@Talh when you take it with the next line being, "it's a recipe passed down in my family," it sounds like they are saying something much more complicated than even that. So I think he's actually calling boiling a flower, and adding honey, a recipe.
Basically making it sound like the back and forth with that merchant from last chapter:
MC: So it looks like there's a hole in your ship keeping you from sailing.
Other person: Oh hoh, sounds like you really know your stuff!
