2
tablespoons unsalted butter, cut into small pieces and softened, plus more for
brushing
3
ounces unsweetened chocolate, very finely chopped
1
teaspoon vanilla, mint or almond extract
1/8
teaspoon kosher salt
1
cup half-and-half
2
1/4 cups sugar
2
tablespoons light corn syrup
Assorted
toppings
Directions
1. Line a 9-by-5-inch loaf pan with foil, leaving a 2-inch
overhang on all sides. Lightly brush the foil with butter.
Lightly brush the bowl of a stand mixer or another large
metal bowl with butter. Add 2 tablespoons cut-up butter, the chocolate, extract
and salt; set the bowl aside.
Heat the half-and-half in a medium pot over medium-high heat
until hot but not boiling. Stir in the sugar and corn syrup and bring to a
boil, stirring constantly and scraping the bottom of the pot with a wooden
spoon; boil, stirring, until the sugar is dissolved, about 3 minutes. Reduce
the heat to low; run a pastry brush dipped in warm water along the sides of the
pan to dissolve any sugar crystals clinging to the pan. Clip a candy
thermometer to the pan. Simmer the mixture, undisturbed, until the thermometer
registers 234 degrees F to 238 degrees F, 20 to 30 minutes, watching the
temperature closely as cooking times may vary. (This is the "soft-ball
stage." To test for doneness, drop some of the mixture into cold water;
you should be able to roll it into a soft ball.)
2. Quickly pour the sugar mixture over the chocolate-butter
mixture in the bowl (do not scrape the sides or bottom of the saucepan in case
any sugar crystals formed). Clean the candy thermometer, then clip it to the
bowl. Let the chocolate mixture cool, undisturbed, until it registers 110
degrees F to 115 degrees F, about 1 hour. (For faster cooling, set the bowl in
a larger bowl of cold water.)
3. Brush the paddle attachment or mixer beaters with butter.
Beat the mixture on medium speed until just incorporated, about 1 minute.
Reduce the mixer speed to low and beat until the fudge just begins to lose its
sheen and hold its shape, 5 to 15 minutes. Do not overmix or the fudge will
become hard. Use a buttered rubber spatula to scrape the fudge into the
prepared pan and pat into an even layer; smooth the top.
4.Press one or more toppings into the fudge, if desired
(about 3/4 cup total). Let sit at room temperature for 1 hour, then score the
fudge into small squares with a knife. For the best texture, let sit at least 1
more hour before slicing. Wrap leftover fudge in plastic wrap and store in an
airtight container for up to 1 week at room temperature, or up to 2 weeks in
the refrigerator. Bring to room temperature before serving.
