How to Make It
Toast sesame seeds in a medium skillet over medium, stirring often, until they smell nutty, 2 to 3 minutes. Transfer to a food processor. Process until finely ground, about 1 minute. Add honey; process until well blended.
Whisk together sesame seed mixture, condensed milk, vanilla, salt, and, if desired, food coloring paste in a large bowl until well combined.
Beat cream with an electric mixer in a separate bowl until stiff peaks form. Fold whipped cream into sesame seed mixture. Pour mixture into a loaf pan or freezer-safe dish. Cover with plastic wrap, and freeze at least 6 hours.
