There’s nothing quite like the satisfaction of taking a warm, fresh loaf of bread out of the oven. Behind this seemingly simple act is a complex interaction between flour, water, heat, and one very small but mighty ingredient is yeast.
Knowing what yeast actually does will help you feel more confident in your bread baking. And when things go wrong, you’ll know where to look.
What Is Yeast?
Yeast is a type of living organism that eats the sugars found in the dough. It produces carbon dioxide, which gets trapped in the dough, causing it to rise. In short, yeast is responsible for turning your flour-and-water mixture into delicious bread.
Temperature Is Key
Yeast is very sensitive to temperature. Heat encourages fermentation, while cold slows it down. But more heat is not necessarily better.
Too Hot
Too-hot water can damage the yeast and prevent it from doing its job. When using yeast, be sure to activate it using warm liquid. If your dough isn’t rising as fast as it should, check the temperature first.
Don’t Rush the Dough
Many beginners rush the dough when making bread. It doesn’t rise on a set schedule. The amount of time it takes depends on a number of things, including the amount of yeast, the temperature, the type of flour, the hydration level, and others.
Watch the Dough
Rather than watching the clock, watch the dough. It should get bigger and puffier. This is one of the most important things you can learn when baking bread.
Kneading is Important
Kneading is how you develop gluten, a protein network that gives bread its structure. Kneading helps align the gluten strands so they can trap the gases produced during fermentation. Without it, the dough would collapse instead of puffing up.
Don’t Count the Minutes
Different doughs need different amounts of kneading. Pay attention to the feel of the dough. A properly kneaded dough will be smooth, elastic, and pliable.
Salt Does More Than Flavor the Dough
Salt affects the fermentation process, as well as the taste of the bread. Using the right amount of salt is essential for getting the balance of flavors you want in your bread. Leaving it out will result in bread that tastes very different.
What Happens During Baking?
When you put your bread in the oven, a number of things happen very quickly. The gases expand, the dough puffs up, and the heat causes the dough to set. The crust browns and takes on flavor.
Troubleshooting Your Yeast
If your bread isn’t rising, there are a number of possibilities.
Your yeast might be dead.
If your yeast is old or has been stored improperly, it might not work.
The temperature might be too low.
Cold slows down fermentation.
The liquid might have been too hot.
Too-hot water kills yeast.
The dough might not have been given enough time.
Fermentation can’t be rushed.
Conclusion
Yeast is a key component of bread-making. Once you understand what it does, you’ll be much better equipped to make great bread. Just remember to pay attention to the temperature, give the dough enough time, and don’t be afraid to experiment.
