There is gelatin in a lot of the bottled dressings you buy in the store. Especially for low fat foods, gelatin is what makes things thick and rich.

The coffee pie is similar to a dessert I have made in "stone soup" situations. I basically added gelatin and more sugar and milk to a cappucino and it made a pretty decent pudding mold.

I went through a phase of gellifying just about any liquid around, though. Green jasmine tea with honey makes a very refreshing summer gelatin, especially when you cut it in cubes and mix into a fruit salad.
