Hot fudge sundae with walnuts.

The story behind the recipe

Bertha E. L. Stockbridge put a hot fudge sundae (in her words, chocolate fudge sauce and nuts over vanilla ice cream) in a book about drinks. Her What to Drink, published in 1920 for the hostess of the dry years, is mostly punches, syrups and shrubs without alcohol, but it gives a chapter to sundaes “Because of the popularity of sundaes, and the preference shown by many for them instead of sweet or fruit drinks.”

Never mussy

Her rules for serving are strict. The ice cream goes in first, “a rounded spoonful,” then the sauce, poured carefully so it doesn’t drip, then just enough nuts “to stay where they are meant to stay.” The glass is a sherbet glass or a wide champagne glass, set on a small plate with a doily and a spoon. “There is one important thing to remember when making sundaes; they must never look mussy!” Pecans were the usual topping, she says, but walnuts do as well, and butternuts if you can find them.

Making it today

Her heavy fudge sauce is chocolate, milk and a great deal of sugar, cooked slowly until smooth and kept hot “in the double boiler or in a chafing dish until ready to serve.” She lists butter and vanilla but doesn’t say when they go in; we stir them in at the end. She asks for two squares of chocolate without saying which kind; her chocolate caramel sauce, four pages on, uses “2 ounces of unsweetened chocolate,” so we use 2 oz unsweetened. The sauce should pour readily, as she asks, and it firms up as it meets the cold ice cream.

Her sundaes close out the dry-years table in What Did Americans Cook When the Bars Closed in 1920?, after the Peanut Cookies (1924) from a Woman’s World summer menu.
