Just one and it's not that inventive. But long before culinary school I was making sweetpotato/pecan pie. The recipe called for making a crumble mixture with the nuts and brown sugar etc. and crumbling it on top after the pie had partially baked. Well I put it on too soon and some of it fell through to the bottom. Well I thought I'd messed it up. It had fallen through before I got to spread it around so I made more but didn't have any butter melted and wanted to get it back in the oven soon so I used honey.
It was wonderful. Now I make the crumble mixture and put it on early and let it fall to the bottom and swirl honey through the pie and finish baking.
eeyore

PS I'm going to try yours though, it sounds wonderful and much more sophisticated than my idea.
