This tart tastes great served warm but if you decide to serve it chilled, turn it out and chill it without the pan. The tart will release lots of liquid, but I found that later it will re-absorb it. Stop cooking the caramel when it turns the color of light tea. Once it begins to change color, that means it's cooking fast. If you want it to stop the cooking, take it off the stove and put a big metal spoon in it.
