Egg sauce
Make as above, beating the yolks of two raw eggs into the thickened milk, and if for fish, adding the yolk and white of a hard-boiled egg chopped fine, also a little minced parsley.
Brown sauce
Make as you would white, but substitute boiling water for the milk, and browned flour for white. Add a teaspoonful of kitchen bouquet, the juice of a lemon, pepper and salt.
Sauce tartare (No. 1)
Make a pint of mayonnaise dressing. Into this beat a teaspoonful of mustard, a tablespoonful of minced parsley, a teaspoonful, each, of chopped pickle and minced capers, a dozen drops of onion juice. Beat for a minute, and serve in a sauceboat.
Sauce tartare (No. 2)
Make a cupful of drawn butter (using boiling water, not milk). Beat in a teaspoonful of French mustard, half as much onion juice, a little cayenne and salt, a heaping teaspoonful of finely-chopped pickle and the beaten yolk of a raw egg at the last.
Hollandaise sauce
Into one cupful of drawn butter beat the yolk of an egg, then a good teaspoonful of best salad oil, dropping as you would for mayonnaise. Add, then, the juice of half a lemon, a pinch of pepper, one of salt, and the same of sugar, and serve at once.
