About 20 years ago I made a souffle and have not made one since. That one worked out just okay. And because I didn't understand the science of it and didn't have internet sources at my disposal to help trouble shoot exactly which step was at fault, I simply abandoned the whole category.
Lately, I decided to go back and master this. Today was the first step, with several data points that I wanted to consider. One, would xantham gum put some backbone in the egg whites? Citronelle chef Michel Richard claims it does, and so I added some. Now here's the stupid part: I didn't do one without so I have no idea exactly what I learned, but I was hoping to get a lot of lift without having to use collars--that was the selling point.
I also wanted to find out if a souffle would work in a square ramekin. I guessed not so well, but wanted to know as I have a lot more square ramekins than round and it would be great for me personally if that worked out. Toward that end, I made two square and two round.
As you can see from the picture below, the round worked beautifully and the squares, not so much. You can see that they didn't peak at all, but what you don't see from the angle I took these at is that each also had a lava flow-like eruption out the other side of the dish.
Back to the drawing board!
