In my younger days I often shook up (in a cobbler!) a Grasshopper as after dinner tipple and this was my primary conveyance of creme de cacao into my belly. Eventually I made a substitution for the cacao and that became my house Grasshopper recipe, if you will. Perhaps I'll revisit it again but that's a story (and an ingredient) for another day.
On occasion creme de cacao appears in small doses in Tiki
