I followed a recipe for creme brulee which called for 4 egg yolks and 2.5 cups of heavy cream and the vanilla, sugar etc. The problem was that it didn't set up the required time (35-40 min) and I had to keep it in the water bath in the oven for atleast 25 additional minutes. After it cooled it was still kinda runny. I checked another recipe this morning and the difference was that the recipe I used did not have me cook the combined mixture before I put it in the ramekins. Can someone tell me if this is a required step? I love creme brulee and would like to have a fool-proof recipe. Thanks.
