Froth Sauce. German. (Mrs. Weston.)
A British version of it.
Put a wineglassful of cooking sherry or light hock into a little
pan, add 1 egg and 3 lumps of sugar, whisk it over a slow fire or
in a pan of boiling water till it comes to a stiff froth. It must
not come near boiling, be in fact not more than new-milk warm.
When the bottom of the pan is hotter than you can touch with
the finger, it is ready.
If not cooked enough, it becomes sloshy again and tastes un-
pleasantly of egg; but if cooked too much, it turns to a bad custard.
