Steam and ears. An epiphony
For a long time I have been trying to get good oven spring and good ears in my loaves.
I have tried all sorts of things, concentrating mainly on developing strength of the dough, adding steam to the oven and slashing correctly.
Results have been disappointing until recently.
I posted a while back showing two loaves made from the very same batch, strengthened and proved in exactly the same way. But I cooked one in a dutch oven and the other right next to it on same shelf.
The results were eye opening. The one cooked in the dutch oven sprung with fantastic ears. The one next to it developed no ears at all.
This helped me to understand that it wasn’t the strength of the dough, the time I gave it to ferment, the way I slashed or any of the myriad other variables that was the problem.
It was simply the amount of steam in the bake.
This frustrated me because both my ovens have steam settings which I have been tinkering with. But the outcomes were never satisfactory.
After more tinkering I have discovered some interesting things.
Injecting steam into the oven is a good thing but what’s more important is keeping it there. So if your oven has good ventilation, it’s quite likely you won’t be able to generate enough steam to give the moisture necessary for good spring.
Luckily, one of my ovens has a setting called ‘moist fan baking’. Moist fan baking shuts off the vent in a supposed effort to make the bake more economical. But for me, it’s a sure fire way to keep steam in the oven.
Whilst the results aren’t quite as dramatic as the oven spring from a dutch oven, they are a significant improvement from bread baked in exactly the same oven but with the vent open.
If you’re wondering why I don’t simply use a Dutch oven all the time, for me it’s simple. They are cumbersome, require asbestos oven gloves and take up so much space in the oven you can only bake one loaf at a time. Whereas with a decent stone, I can bake three loaves on that stone, thereby reducing oven use by two thirds.
The loaves pictured below were baked for 10 mins at the highest steam setting (3) at 130 which is the highest it will go (It’s a setting normally reserved for custards etc). This setting still vents the steam though. I then switched to moist fan baking for 25 mins where I’m able to whack up the heat to 230.
Next batch I will try Moist fan baking for the whole bake but use the boiling tray of water at the bottom for the steam creation. I won’t be able to create steam via the oven because I’m not on a steam setting, I'm on Moist fan baking. Very frustrating!
So my conclusions thus far after many years of obsessing about spring and ears is this. For sure, take care of your surface tension, your ferment time, your slashing. But none of this will mean anything unless you’ve got a reasonable way of trapping steam around the loaf. All ovens are different and if yours vents well, you will still bake nice bread but it really won’t spring or get ears. Well mine certainly don’t anyway!
Spraying the loaves as they go into the oven also helps.
I believe starting on a lower oven temp also helps (130-150) but I still need to experiment on that.
Or you could just forego the pretty risen loaves altogether and do a focaccia instead! No ears needed, comes out great every time.
Any alternative/extra thoughts gratefully received btw. I’m no expert but years of failure have led me these conclusions and I wanted to share. Cheers.
Regarding Dutch ovens: Try metal roasting pans. Lots of previous threads on this in the Archives.
This one is about 15" overall.
I've never considered a roasting pan. Instinctively it feels like it wouldn't work like putting the dough straight on the stone but judging by your beautiful loaf it does. That and tin foil may be the perfect combo. I'll experiment. Thank you.
The frustration of having to choose between multiple loaves vs one well-steamed loaf is real. I have thought about making a tin foil lid for my biggest roasting pan, which will hold 3 batards side by side. I would preheat the oven with a pizza stone in it, load the loaves into and seal up the roasting pan cold, and set it on the stone. Then carefully use tongs to remove the foil after 20 minutes or so, so as not to get scalded by steam.
My oval lidded roasting pan will hold two small un-rimmed sandwich loaf tins, which is very satisfying.
I have never even considered tin foil. That's a genius idea and one I'm going to try. Thank you.
This was my thinking process about making a roasting pan lid from foil:
My oven doesn't have steam, but it does have an accessible vent opening. Maybe this is a dumb question, but is it not possible to plug up the vent with a tea towel, thus keeping the steam inside?
I plug the vents on my oven door with wads of foil before filling the trays to generate steam. It works like a charm. My oven is rather old, and the door opens to the side, so vents are on the side of the door.
This won't work if your oven is a gas oven, where you can't plug the vents.
I do that, but it just forces all the steam to come out of the door gasket, which in my old oven doesn't seal very well. The bulk of the steam is over in a few minutes. Still, I get a small improvement. You have to watch out and remove the plug when the steam is finished, otherwise it can start to scorch.
With modern ovens and all their electronics, I would be concerned that if the vents were well plugged up, some steam would escape into the control areas and lead to early failure.
