Mexican Chocolate Sauce

This Mexican-style chocolate sauce is dark, rich, and spiked with Kahlua coffee liqueur for a warm, boozy depth that plain hot fudge can’t match. Pour it over ice cream, drizzle it on pound cake, or spoon it into a cup of hot milk for the richest drinking chocolate you’ve ever had.

Cooking everything together in a double boiler for 10 minutes lets the unsweetened chocolate melt smoothly into the butter, cream, and corn syrup without any risk of scorching. The constant stirring keeps the texture silky and prevents the sugar from crystallizing.

The Kahlua isn’t just for flavor. The alcohol helps the sauce stay pourable even when cold, so you can pour it straight from the jar in the fridge without reheating. Though warming it in a pan of hot water brings out the best aroma and flow.

This sauce stores in a sealed jar for up to three months in the refrigerator, making it a fantastic homemade gift.

Chef Tips

• Use unsweetened chocolate for the deepest, most intense flavor. Semisweet makes the sauce too sweet since there’s already sugar and corn syrup in the mix.
• Stir constantly for the full 10 minutes. Walk away and the bottom scorches, leaving you with gritty bits in an otherwise smooth sauce.
• Pour into a warm jar while the sauce is still hot. Cold glass can cause the chocolate to seize.
• Reheat gently in a pan of hot water, never in the microwave. Microwaving causes uneven heating and can break the emulsion.

Variations

• Spicy Mexican chocolate: Add a pinch of cayenne pepper and a ¼ teaspoon of cinnamon for a traditional Mexican hot chocolate flavor.
• Bourbon chocolate: Swap the Kahlua for bourbon for a deeper, smokier kick.
• Non-alcoholic: Replace the liqueur with strong brewed coffee for the same mocha flavor without the alcohol.
