“It will expand the way people drink coffee,” says Puck, the celebrity chef with a growing empire.

How does the can do it? A single step mixes calcium oxide (quicklime) and water. It heats the coffee to 145 degrees in six minutes and stays hot for 30 minutes.

  1. Yeah … I like my coffee without quicklime, thank you. Even if calcium oxide doesn’t leave a lingering taste, I still don’t see how this can be better than Sanka or Folger’s crystals.

  2. That will certainly be helpful to residents. Then they don’t have to run down to the caf to grab something.

  3. Hah! A fellow coffee addict!

  4. Answer: 2 weeks

    Question: What is the length of time it will take for some idiot to burn himself and spark a lawsuit Alex?
