Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Red Currant Ice
Ingredients
Directions
Prepare the fruit
Strip currants from stalks and combine with raspberries.
Rub the mixture through a fine sieve.
Sweeten and flavor
Add enough cold syrup or sugar to sweeten the mixture.
If desired, add lemon juice for extra flavor.
Freeze
Freeze the mixture using an ice cream maker, scraping the sides to ensure smoothness.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Red currants
- Provide the tart, acidic flavor and much of the pectin that gives the base its body.
- Raspberries
- Add sweet aroma and a deeper fruit flavor to the currant base.
- Sugar
- Sweetens the base and lowers its freezing point, keeping the ice cream softer and scoopable.
- Lemon juice
- Adds acidity that brightens the fruit flavor and balances the sweetness.
The step that matters
Freeze the mixture using an ice cream maker, scraping the sides to ensure smoothness.. Churning while scraping the sides keeps ice crystals small and evenly distributed, so the ice cream turns out smooth rather than grainy or icy.
Swap the currant
How well each one fits the dish's main ingredients (sugar, lemon):
- Orangefits better
- Limefits better
- Vanillafits better
- Currantthe original
Fit is the average pairing score against sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
