Topic: Adventures in Steam
As I noted a few days ago, I've been experimenting with using some heat-safe food grade silicone tubing to add water to a hot cast iron skillet to generate steam in my oven without opening the door. The first bit of good news is that the tubing doesn't seem to be causing a heat leak around the oven door, so I can leave it in most of the time.
I've been doing some math on steam generation. My bigger oven is about 3.6 cubic feet. (It'll hold a full size sheet pan but with almost no room for air circulation, so I stick to 3/4 sheet pans.)
In some tests, it looks like I can put about 20 CCs of boiling water into the pan via the tubing and have it vaporize in a few seconds. When water converts to steam, it expands to about 1600 times its volume. So 20 CCs of water will generate about 32,000 CCs of steam or about 1.1 cubic foot, meaning the oven chamber should be about 1/3 steam briefly.
I don't know how that compares to the amount of steam you get in a commercial steam injection oven each time you pull the lever, because I've never used one. I'll see if I can find some data on one.
A possibly major difference between a commercial steam injection oven and a home oven is that the commercial oven has vents that can be sealed to keep the steam in for a while, a home oven is probably far less air tight. (I know there's some kind of vent at the back right because I can feel the heat there when the oven is in use. And after the oven has been on a while, a fan kicks in, I'm assuming it pulls some of the air out of the oven so it would pull out steam as well.)
I will be taking some pictures showing my setup, and I'm going to try to take some videos showing how much steam it generates, possibly compared with the 'pour water in the pan' method.
The videos will mostly be with the door open, though I may see if I can set the camera up to shoot through the oven door. Where's Alton Brown's oven camera when you need it?
I'm also getting ready to try my steam generator with some recipes I know, so I can compare the results. I may have to try to bake a recipe at least 3 times, once without steam, once with the 'pour the water in the pan' method and once with the tubing method, and maybe a few other ways.
On Sunday morning, I took a break from the steel-cut oats and made a half recipe of the Cornmeal-Rye Waffles in the King Arthur Whole Grain Baking Book (p. 21). These are completely whole grain, using cornmeal and pumpernickel flour. I replaced the 3 Tbs. of melted butter with equivalent canola oil. It's an excellent recipe, and with the whole grains, I don't miss the butter. A half recipe made 7 waffles, and we had no problem consuming all of them.
