Miss Parola's Chocolate Frosting

1 square of Baker's Chocolate,
Pinch of salt,
5 tablespoonfuls of boiling water,
1 teaspoonful of vanilla,
About three cups of sifted confectioners' sugar.

Melt chocolate in bowl over tea-kettle, add water, salt and vanilla, and when smooth add the sugar, and heat until very glossy. Make the frosting stiff enough to spread without using a wet knife. It will keep indefinitely.
