Chocolate and oranges

I had this sudden craving for these two flavours together, at the beginning of this week, so purchased three likely looking oranges (and checked our cocoa stores. As always, the level was high. Ha!).

I used this recipe for chocolate orange sticks, as it looked to be the easiest. It was still a special kind of hell (that took hours) on account of how fiddly it was, and I have a new-found respect for my mother's efforts each Christmas as I was growing up.

I also decided to try my hand at chocolate-orange cake, using the juice of my oranges. I altered the chocolate orange muffin recipe over here by substituting one of the eggs with about 180mLs of orange juice (all of what my oranges gave up). I ended up with a kind of fudge-consistency sweet and sharp cake thing. It is very tasty, but I think next time I'll use less juice.

Now, does anyone know what I can do with 2/3 cup sugar syrup and 4 litres of orange water?
