Hot Fudge Sauce

Real hot fudge sauce starts with unsweetened chocolate, not cocoa powder, and you can taste the difference. Three ounces of solid chocolate melted into a sugar-flour base with butter and vanilla creates a thick, glossy sauce that clings to ice cream instead of running off into a puddle.

The flour-sugar mixture gets cooked with water first until it thickens into a syrup. This creates the body of the sauce before the chocolate goes in. Adding chocolate to the thickened base means it melts evenly without seizing or turning grainy.

Butter beaten in at the end adds richness and a silky sheen. The vanilla goes in last since heat destroys its delicate flavor.

Beat the sauce occasionally as it cools. This keeps it smooth and prevents a skin from forming on the surface.

Pro Tips

• Use real unsweetened baking chocolate, not chocolate chips. Chips contain stabilizers that affect the texture of the sauce.
• Stir constantly while the sugar-flour mixture heats. Flour clumps and burns fast if left unattended.
• For a richer sauce, replace the water with evaporated milk. It makes the fudge creamier and more ice-cream-parlor worthy.
• Store in a jar in the refrigerator for up to 2 weeks. Reheat gently in the microwave or a double boiler before serving.

Variations

• Mocha fudge: Add a tablespoon of instant espresso powder to the sugar-flour mixture for a coffee-chocolate sauce.
• Mexican chocolate: Stir in a pinch of cinnamon and cayenne for a spiced fudge sauce with subtle heat.
