Ekmek Neden Kabarır — A2–B1 İngilizce Okuma Parçası

Bread is made from very simple things: flour, water, salt, and a little yeast. Mix them and you get a heavy, flat piece of dough. Leave it alone for an hour or two and it grows. Put it in a hot oven and it grows again, then holds its shape. Nothing was added. So where does the extra size come from?

The answer is that one of those four things is alive. Yeast is not a powder like salt; it is a very small living thing, so small that a spoonful holds many millions of them. When the yeast meets water and flour, it starts to eat. What it eats is the sugar that is already in the flour, and while it eats it gives off a gas.

That gas has nowhere to go. The dough around it is soft but it holds together, so the gas stays inside and forms thousands of small bubbles. As more gas is made, the bubbles grow and push the dough out in every direction. This is why bread rises without anyone touching it. The dough is not being filled with air from outside; it is being filled from within.

Warmth changes the speed of all this. In a warm kitchen the yeast works quickly and the dough may double in an hour. In a cold room the same dough will take much longer, because the yeast slows down when it is cold. Bakers use this: if they want to make bread in the morning, they leave the dough in a cool place all night.

The oven does two more things. First, the heat makes the gas expand, so the bubbles get bigger one last time. Then the outside of the dough dries and turns hard and brown, and the bread stops growing. The yeast itself dies in that heat, its work finished.

Cut a piece of bread and look closely at it. The soft part is full of holes of every size, and each one is the place where a bubble used to be. They are the record of a gas that has gone. A piece of bread is really a picture of something that happened to it hours before it reached your table.
