Place mixing bowl and beater(s) of an electric stand or hand mixer in the freezer for at least 30 minutes. Whisk attachment is best but regular beaters will do. Remove from freezer.
Pour whipping cream into cold bowl.
Using the cold beater, mix on low speed for about 15 seconds, then beat on high speed until stiff peaks form. This will take about 2 minutes. Cream should hold firmly to your whisk when you lift it out of the cream.
Gently fold in the condensed milk into the cream with a rubber spatula. To fold: start your spatula at the side of the bowl, slowly swipe the spatula down to the bottom of the bowl and lift up and across to the opposite side, combining the two ingredients. Rotate the bowl turning the cream and milk on top of each other and continue folding until the two are combined.
Repeat this gentle folding method with the honey and sea salt.
Pour into a freezer-safe container. Drizzle top of ice cream with honey. Cover and place in freezer for at least 6 hours.
