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 ↓
White Currant Jam, a Beautiful Preserve
Ingredients
Directions
Boil equal quantities of white currants and sugar together quickly for seven minutes.
Stir the mixture gently the whole time and skim thoroughly.
Just before removing from heat, add the strained juice of one lemon.

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
- White currants
- Provide the fruit flavor and natural pectin that helps the jam set as it cooks.
- Sugar
- Sweetens the jam, helps it set, and preserves it for storage.
- Lemon juice
- Adds acidity that brightens the flavor and supports pectin setting.
The step that matters
Boil quickly for seven minutes while stirring. A brisk boil reaches the concentration needed for the jam to set. Constant stirring keeps the dense sugar syrup from scorching on the bottom of the pan, which would give a burnt, bitter taste.
Swap the white currant
How well each one fits the dish's main ingredients (sugar, lemon):
- Orangefits better
- Limefits better
- Vanillafits better
- White 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.
