For the record, there are two types of yeast. One is traditional yeast, which you use the sponge method for. That’s what we’ll be going over here.
The other kind is instant yeast. This is also known as rapid rise or bread machine yeast. Basically, you just toss it in with everything else and there is no need to do the sponge method. It’s convenient but I tend to dig the tradition of the sponge process. It’s science-y and cool, and it breaks the process into do-it-quick steps. As the mama of two small trapeze artists, I appreciate that.
If, like me, you have followed a recipe without paying any attention to what kind of yeast is called for, you might have ended up with a dough that contains little balls of yeast in the finished product. It also doesn’t rise properly, resulting in a dense, heavy bread. So if your recipe calls for instant yeast and you don’t have any, you need to do the sponge method. The two types of yeast are generally interchangeable, provided you follow the proper method for whatever kind you have.
The Sponge Method
Maybe you know this, maybe you don’t, but yeast is a living organism. You always begin a traditional yeasted dough with the process of combining the yeast, a sugar, and warm water. These are the only three ingredients that are put together in the beginning.
- The yeast feeds on the sweetener (sugar, honey, agave, what have you) and the warm water creates a peaceful, supportive environment for the event to happen.
- Ideally, the water should be about 100–105 degrees (almost too hot on the tender part of your wrist). To ascertain the temperature, use a meat thermomtraeter to gauge the feel of the water. Commit this feeling to memory, or use a thermometer every time if that works for you.
When the conditions are ideal, this will happen in about five minutes:
This is what is known as “the sponge”. Basically it’s a bowl of foamy goop. There are rules to yeast, but don’t be afraid of it. If the water is too hot it will kill the organisms, if the water is too cold the process will take FOREVER.
The feeding frenzy must be stopped at the foamy goop point or else the yeast will overproof (gorge itself and die) and won’t work in your dough.
How on earth do you stop the madness of this hungry yeast? Add your salt. That’s it. And technically it doesn’t stop it, it just slows the process down to the point where you can add the rest of the ingredients and give the yeast some real work to do. You don’t want to add your salt prior to this point though because your bread will turn out dense and brick-like.
