A Good Sauce for Puddings ( Miss Amelia Foote ).
Ingredients: Half a cupful of butter, one cupful of sugar, white of one egg, two table-spoonfuls of wine, a little vanilla, and half a wine-glassful of boiling water.
Beat the butter and sugar for about fifteen minutes; then add the flavoring. Just before sending to the table, add the egg, beaten to a froth, and stir in the boiling water, beating it to a foam; or it may be flavored with brandy or wine, without the vanilla.
