2/so, after 55 minutes of cooking add some (little) salt and continue a slow boiling during 20 minutes (test the degree of cooking of the beans from time to time : the cooking time depends on the age of the beans) uncovered
3/ when the beans are cooked, get rid of the bones bag, blend the beans with the other vegetables and the water and sieve thoroughly so that the maximum of the bean material come through the sieve
4/ put the bean purée onto the heat with the liquid cream, adjust seasoning and at the last moment, add 0.7 oz cold butter cut into small dice
