We have a neighbor who takes care of our cats when we're gone. Sometimes she'll stay for a while and watch TV as she doesn't have cable. One day when she was over, we asked her if she wanted something to drink. She asked if she could have some of "that coffee from the jar we keep in the fridge". It took us a while to figure out that she meant the instant espresso. Apparently, she noticed that when she was over one day and has been making "coffee" with it.
Other than that, we've just used it for baking.
