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 ↓
Preserves
Ingredients
Directions
Prepare the fruit
Prepare the fruit and place it in wide-mouthed bottles.
Sprinkle 6 ounces of sugar over the fruit.
Reserve 2 ounces of sugar for later.
Cook the fruit
Place the bottles in a pan of cold water and gradually heat.
Simmer for 30 minutes.
Fill the bottles from each other.
Make the syrup and finish
For syrup, combine 12 to 32 ounces of sugar with 1 pint of water and simmer with lemon slices for 5 minutes.
Strain the syrup.
Let the syrup cool.
Add the fruit in thin slices to the syrup.
Simmer until the fruit is tender.
Transfer the preserves to jars.

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
- Fruit
- Provides the main flavor and body of the preserves.
- Sugar
- Sweetens the preserves and helps draw out moisture and thicken the syrup.
- Lemon
- Adds acidity that brightens the flavor and helps the fruit set.
The step that matters
Simmer until the fruit is tender. Cooking the fruit gently until just tender keeps its shape and texture. Overcooking breaks the slices down and makes the preserves mushy.
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.
