Hot Fudge Sauce

This is not my own creation - I've had this recipe for a while and I can't remember what magazine I got it from, so you'll have to forgive me on the credits. But, I have made it several times before. This sauce keeps in the refrigerator for 3 months.

Good chocolate makes a huge difference here, splurge on it for this.

1/4 cup unsweetened cocoa powder (natural or Dutch processed)
2/3 cup heavy cream
2 cups light corn syrup
1 pound semisweet chocolate, coarsely chopped
5 Tablespoons unsalted butter
pinch of table salt

Put the cocoa in a heavy-based saucepan. Slowly pour in the cream and whisk until smooth. Add the corn syrup, chopped chocolate, butter and salt. Set the pan over medium heat, stirring occasionally to combine. When the chocolate is melted and the mixture comes to a boil, reduce the that and let boil gently until slightly thickened, about 5 minutes. 

Let the sauce cool until it's just warm (steam should no longer rise from the sauce when it's stirred) and pour into jars. Refrigerate.

Put a ribbon and tag around the jar to give as a gift.
