Add the stock.

Stir and cook well.

Then stir in the cream; let it boil in the sauce; and add lemon juice, pepper, and salt.

Strain through a tammy-cloth.

Milk may be substituted for the white stock, if more convenient. To flavour it, a small piece of carrot, turnip, and onion, and 6 button mushrooms should be boiled in it.

Sauce Hollandaise.

Method.—Put the white sauce and eggs into a jug, which must be placed in a saucepan of boiling water.

Stir until the mixture thickens, being careful it does not curdle.

When quite ready, add the lemon juice or vinegar.
