Why it works: Cream and lemon are a kitchen classic. They rank in the top 30% of all ingredient pairs, and cooks put them together in 15,640 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Barberry Ice Cream
Ingredients
Directions
Make the base
Combine barberry jam, heavy cream, and lemon juice in a bowl and mix well.
Add a little cochineal to the mixture to color it.
Pour the mixture into a freezing pot and cover it.
Freeze
Place the freezing pot into a pail surrounded by ice.
Sprinkle coarse sea salt on the ice and turn the pot for 10 minutes.
Open the pot and scrape the sides.
Cover it again and continue turning until thick.
Mold and serve
Transfer the mixture into molds.
Place the molds back in the pail, covering with ice and salt for 45 minutes.
Once the water rises to the top of the pail, dip the molds in water.
Turn them out onto a plate to serve.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: acetic acid (sour, vinegar).
Cream and lemon barely smell alike, yet cooks put them together in 15,640 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barberry jam
- Provides sweetness, fruit flavor and tartness that define the ice cream.
- Heavy cream
- Adds fat, which gives the frozen ice cream a smooth, rich texture.
- Lemon juice
- Adds acidity that brightens the flavor and balances the sweetness of the jam.
- Cochineal
- Adds red color to the mixture without changing its flavor.
The step that matters
Turning the pot in the ice and salt. Salt lowers the melting point of the ice, letting the mixture get colder than ice alone. Scraping the sides and turning keep ice crystals small and the texture smooth; stopping too early leaves it icy.
