STAUBBouillabaisse Pot 28 cm Dark Blue

Q: What is the difference between a braiser and a bouillabaisse pan?

Probably only the shape and depth. Braising is cooking a dish in a small amount of liquid. The pan itself must be covered in order to retain the moisture while cooking. Bouillabaisse pots tend to be shallower than other covered pans (like Dutch ovens).
