The omelette des matelots is a speciality in its way. Make a purée of anchovies with five or six anchovies well freed from oil. Moisten this with a tablespoonful of white sauce, and mix it with six eggs when finishing the omelette mixture. Prepare some neat slices of smoked salmon, warming them in butter. Make the omelette, dish as already described, and arrange the slices of smoked salmon along its upper side at the last moment.
