Blend the Sesame Seeds: In a blender or food processor, add the black sesame seeds and honey. Blend until the mixture forms a smooth paste. Set aside.
Heat the Cocoa Mixture: In a medium saucepan, combine the black cocoa powder, sweetened condensed milk, and salt. Stir in the blended sesame seed mixture, and cook over medium heat, stirring constantly, until everything is well combined and smooth. Remove from heat and stir in the vanilla extract. Let the mixture cool to room temperature.
Whip the Cream: In a large bowl, whip the heavy cream using a hand mixer or stand mixer until soft peaks form. Be careful not to over-whip.
Fold Ingredients Together: Gently fold the cooled black sesame and cocoa mixture into the whipped cream, taking care to preserve the airy texture of the cream. Continue folding until the mixture is well combined and smooth.
Chill and Freeze: Pour the ice cream mixture into a loaf pan and smooth the top. Cover with plastic wrap or foil, and place in the freezer for at least 6 hours, or until firm.
Serve: Once fully frozen, scoop and enjoy your Cruella De Vil (Cocoa Black Sesame) Ice Cream!
