I am making the Ulimate Cheesecake recipe from this website. I have cooked it for an hour like it says. It say cook it till it's set. What does that mean? I have never make a cheesecake before. I took it out of the oven and tapped it a bit and it is still very liquidy. How do I know when it's set?

It should still be a little jiggly in the middle - a bit firmer on the edges. It will not look done. Usually if you use the size pan recommended, you can trust the baking time stated.

Thank you. I just checked it and it is slightly jiggly in middle but sides are firm. I am taking it out now. Thanks again!

One more thing: run a knife around the edge to loosen - otherwise the top may crack. If you're putting fruit or something on the top, it's not as important.

Do that after it has cooled in the fridge right?

Ok so the cheesecake looks beautiful until we cut into it. It was still liquid in the middle. I cooked it longer then it said too so I don't know what happened. Any ideas?
