The black round thing in pizza is usually a black olive.
Black olives are a popular pizza topping, known for their salty and slightly bitter flavor. They add a contrasting element to the often sweet and savory flavors of pizza.
Here are some other possibilities:
- Pepperoni: Pepperoni, while usually red, can sometimes appear black depending on the lighting and the type of pepperoni used.
- Mushrooms: Some mushroom varieties, like black trumpet mushrooms, have a dark, almost black color.
- Charred crust: The crust of a pizza can sometimes become charred, resulting in a black, crispy edge.
Note: It's important to consider the context of the question when determining the answer. If the question is about a specific pizza or image, additional information might be needed to identify the black round thing.
