In a saucepan, stir together sugar, cocoa, cornstarch and salt. Place over medium heat, and stir in milk. Bring to a boil, and cook, stirring constantly, until mixture thickens enough to coat the back of a metal spoon. Remove from heat, and stir in butter and vanilla. Let cool briefly, and serve warm, or chill in refrigerator until serving.
1/2 cup (170 grams) light corn syrup, golden syrup, or honey
1/4 cup (50 grams) packed dark-brown sugar
1/4 cup (20 grams) cocoa powder
1/4 teaspoon fine or table sea salt
6 ounces (170 grams) semi- or bittersweet chocolate, chopped, or 1 cup semi- or bittersweet chocolate chips
1/2 teaspoon vanilla extract
Combine the butter, cream, sweeteners, cocoa, and salt in a small saucepan over medium heat and bring to a simmer. Simmer on low, stirring, for 3 to 5 more minutes after everything has melted, then remove from heat and stir in chopped chocolate or chocolate chips. Stir in vanilla.
It’s now ready to ladle over ice cream, although it thickens more as it begins to cool, so you could also wait for 15 to 20 minutes before doing so, if it’s not too unbearable. Pour leftovers into a jar or jars and refrigerate. Hot fudge sauce keeps chilled in the fridge at least a month and often two, although it’s rare it lasts that long.
1 cup unsweetened cocoa powder, preferably Dutch process
2 1/2 cups nonfat dry milk powder
1 teaspoon fine-grain salt
2 teaspoons cornstarch
1 pinch (or more to taste) ground cayenne pepper*, optional
Hot milk or water to serve
Combine the confectioners’ sugar, cocoa powder, milk powder, salt, cornstarch and cayenne in a large airtight container. Secure the lid and shake vigorously to combine, and remember to shake prior to every extraction.
To serve: Place 2 tablespoons of the mix in a mug and add about 2 fluid ounces hot water or milk. Stir to combine. Fill the mug with more hot water or milk and enjoy.
* The Aztecs always added chiles to their chocolate. Even a pinch ups the flavor ante quite a bit, and as called for here certainly won’t be sensed as “heat.”
No matter — this is fast, easy and will keep for a year if kept in an airtight container in a cool place.
To make hot chocolate: Bring the milk, water, and sugar just to the boil in a medium saucepan. Remove the pan from the heat and whisk in the chocolate. The hot chocolate needs to be blended at this point. At Ladurée, this is done with a hand-held blender (also called an immersion blender). If you have this tool, leave the hot chocolate in the saucepan and whip it with the hand-held blender for 1 minute. If you don’t have a hand-held blender, transfer the chocolate to a traditional blender and whip on high speed for 1 minute. (When blending hot liquids, be sure to remove the center insert from the top of the blender, and cover the top with a folded kitchen towel to allow steam to escape.) The chocolate should be served immediately, while it is still very hot and frothy. Alternatively, you can pour the chocolate into a container to cool; the cooled chocolate can be reheated or served chilled. (The chocolate can be made up to 2 days ahead and kept tightly covered in the refrigerator.)
To reheat chilled hot chocolate: Working in a medium saucepan over low heat, warm the chocolate, stirring gently, just until the first bubble pops on the surface. Pull the pan from the heat, whip the chocolate for 1 minute with a hand-held blender (or in a traditional blender), and serve immediately.
To make cold hot chocolate: Chill the hot chocolate until it is very cold, then stir in 3/4 cup (200 grams) cold milk. Whip the cold chocolate for 1 minute with a hand-held blender (or in a traditional blender). Serve the cold hot chocolate over an ice cube or two.
Keeping: Once blended, the hot chocolate can be cooled and refrigerated in a tightly sealed jar for 2 days; reheat gently, or serve as cold hot chocolate.
Cold hot chocolate makes a fabulous ice cream float. Greenspan whips the cold chocolate to froth, pours it into a tall glass — beer glasses are great for this — and adds ice cream. While the traditional go-with-chocolate flavors, like vanilla, coffee, vanilla-fudge, and chocolate in all its renditions, are always good, her favorite floatable flavor is Ben & Jerry’s Cherry Garcia. serves 4
