The dough is the basis of alimentation in Benin. It is made from freshly ground cereals (millet, corn). In the kitchen of the canteen of the college of Champagnat, it is not easy to have everyday and at the right time the flour necessary for feeding the 134 students who take their meals there. The mills of the city operate irregularly, victims of unforeseen events, breakdowns, mismanagement, fuel breaks, etc. It is common to have to travel all over the city in search of an open mill. This disrupts the pace of classes, as students cannot eat at the scheduled time.
