Wash the sweetbreads thoroughly and let them stand in cold water half an hour. Boil in salted water twenty minutes and then put in cold water again for a few minutes, to harden. To one cupful of minced sweetbreads add one cupful of diced celery and one-half cupful of chopped nuts. Cover well with mayonnaise dressing to which some whipped cream has been added.
Drain and press through a sieve a can of green peas. Dissolve one box of gelatine in one-fourth of a cup of cold water and stir over a hot fire until heated. Take from the fire and add one-fourth teaspoonful of onion juice, one-half teaspoonful of salt, and a dash of pepper. Serve very cold with the following dressing: Put into a double boiler the yolks of two eggs, two table-spoonfuls of stock and two tablespoonfuls of oil. Stir until thick, take from the fire and add slowly one tablespoonful of tarragon vinegar, one chopped olive and two teaspoonfuls of chopped parsley.
