Carefully skim off the foam. Simmer everything over low heat for about 45 minutes, stirring occasionally. Then pass the liquid through a fine sieve, carefully add a little salt and allow to cool.
Skim off any existing fat layer when it is cold or degrease it with kitchen paper. This stock should be stable for a week in the refrigerator. You can also freeze it in portions.
