But when a freshly prepared pizza contains ordinary cheese blisters, there is generally no reason to become alarmed by the bubbles themselves.
They are often just part of the cooking process.
18. A Final Thought: Sometimes the Smallest Details Have the Most Interesting Explanations
When I first noticed unusual bubbles scattered across the cheese on a pizza, I wondered whether something had gone wrong.
The surface looked different from what I expected.
Some areas appeared smooth, while others were raised, golden, and slightly blistered.
It was easy to imagine that the cheese had reacted strangely or that the pizza had been overheated.
But learning more about the cooking process changed the way I looked at it.

The moisture inside the cheese begins to evaporate.
Steam and air expand.
The softened cheese stretches around the trapped gases.
And as the surface continues heating, some areas turn golden brown.
