Originally, bouillabaise would be made by fishermen in Marseilles and the French Mediterranean coast to use up any unsold fish and trimmings. These days, it tends to be a little more fancy. For the best flavour, make your own fish stock.

Working in batches, whizz the pan contents in a blender until smooth, then place a colander over a large bowl, line it with cheesecloth, and strain the mush through it. You'll probably need to gather the cloth into a ball, spin it, squeeze it and massage it until you've extracted as much liquid as possible. Pressing it with the back of a spoon through a fine sieve can also work. At the end of the process, strain the liquid through a fresh cloth. Taste for seasoning, add salt if necessary.
