Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Neapolitan Ice Cream
Ingredients
Directions
Prepare the cream
Freeze 1 gallon of cream until hard, then divide it into three equal parts.
Color one part with chocolate, another with rose or strawberry, and flavor the last with vanilla.
Layer and freeze
Layer the colors in brick-shaped molds: first red, then white, and finally chocolate.
Close the molds tightly and pack them in ice and salt.
Allow to freeze for 3 to 4 hours.
Unmold and serve
Dip the molds in hot water, remove the lids, and turn out onto a cold board.
Cut into slices across the layers and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Freezes into the rich, smooth body of the ice cream.
- Chocolate
- Colors one layer and adds cocoa flavor.
- Rose or strawberry flavoring
- Colors and flavors the red layer.
- Vanilla
- Flavors the white layer.
The step that matters
Dip the molds in hot water. A brief dip warms only the outer surface of the mold, loosening the ice cream so it releases whole. Too long a dip melts the outer layers and blurs the stripes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
