Chocolate Ice Cream

This is the kind of chocolate ice cream made for a screened porch and a paddle freezer packed with rock salt, the way grandparents did it before electric machines took over the kitchen. The base leans on a cornstarch-thickened milk custard instead of an egg-only one. That’s why the texture stays creamy even after a few days in the deep freeze. Cornstarch holds water in a way pure egg yolks can’t.

The trick is the order of operations. Whisk cornstarch into cold milk first so it doesn’t clump, then cook it slow until it coats the spoon. Beat the hot starch mixture into the sugar and eggs while everything is still warm so the custard tightens evenly. Stirring constantly during that initial cook is key. Walk away and you’ll fish lumps out for the rest of the night.

Semi-sweet chocolate keeps the sweetness in check, while evaporated milk and heavy whipping cream layer in body and richness. After churning, let it season several hours covered in the freezer. That ripening step firms the texture and lets the vanilla bloom.

Pro Tips

• Chill the custard fully before churning. A cold base freezes faster, which means smaller ice crystals and a smoother scoop.
• Chop the chocolate fine and melt it into the warm custard so it disperses cleanly. Lumps freeze rock hard.
• Don’t overpack the freezer canister. Leave headspace for the cream to expand as it churns.
• Rock salt with crushed ice should be a 1:6 ratio for the bucket. Too much salt freezes too fast and makes the texture grainy.

Variations

• Stir in chopped roasted pecans or toasted almonds during the last minute of churning.
• Swap an ounce of the semi-sweet chocolate for unsweetened cocoa for a deeper, darker flavor.
• Add a teaspoon of espresso powder to the custard. Coffee makes chocolate taste more chocolatey.
