I did it this time as well and must have done it the first time I made this.
But it was SOOO liquid-y at 35 minutes (nothing seemed set, not even the edges) that I worried it won't set up once outside the oven, even sitting in the hot water. And I needed it to work.
So, good to know. Either you can cook it for an hour--or cook it 35 minutes and let it sit.
