I wondered if using dark brown sugar would change caramel-making. Well, the making is the same. The results were slightly different but positive.
Here’s how to go about it:
Brown sugar caramels
1½ cups heavy cream
¼ cup unsalted butter
Pinch of salt
1 cup dark brown sugar
½ cup granulated sugar
¼ cup light corn syrup or golden syrup
¼ cup water
1½ teaspoons vanilla
Sea salt to top, if desired
Lightly oil or spray an 8×8-inch square pan and line with parchment paper (the baking spray helps keep the parchment in place). Set aside.
Heat the cream, butter and salt in a small saucepan and heat together over medium-low heat until cream steams and butter is melted. (Or do the same in a microwave-safe bowl in the microwave on high in 30-second intervals until cream is hot and steamy and the butter is melted, stirring or swirling gently between microwave intervals.) Set aside.
In a large heavy-bottomed pot add the sugars, syrup and water. Whisk until thick and grainy. Clip your candy thermometer to the side of the pot, making sure the tip is submerged but not touching the bottom of the pot.
Turn the heat to medium. Without stirring, heat to 260 degrees F. Remove from heat, then slowly whisk in the cream mixture. Mixture will boil up so do this carefully.
Return to heat and, again without stirring, heat to 250 degrees. Turn off heat, quickly but gently whisk in the vanilla, and carefully pour into the prepared pan. Do not scrape the bottom of the pot, as this will have burned sugar that you do not want in your caramels.
Top caramels lightly with coarse sea salt, if desired. Allow to cool completely, at least 2-3 hours or, preferably, overnight. Cut into squares or rectangles and wrap each piece in waxed paper.
