Why it works: Lemon and sugar 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 ↓
Medlar Jelly
Ingredients
Directions
Prepare and cook the medlars
Choose ripe medlars and place them in a preserving pan.
Cover the medlars with cold water and boil for 20 minutes.
Strain and flavour
Strain the mixture through a sieve without pressing the medlars.
Weigh the juice and return it to the pan.
Add the rind and strained juice of 1 lemon for every 100 medlars.
Set and jar
Once the jelly is clear, remove the lemon peel and pour into small glass jars.

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.

Lemon and sugar 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
- Medlars
- Provide the fruit flavour and the natural pectin that helps the juice set into jelly.
- Sugar
- Adds sweetness and, with the fruit's pectin and acid, helps the jelly set firm.
- Lemon juice
- Adds acidity that brightens the flavour and supports pectin setting.
- Lemon rind
- Adds aromatic lemon oils to the juice while it cooks.
The step that matters
Strain without pressing the medlars. Pressing forces fine pulp through the sieve, which makes the jelly cloudy. Letting the juice drip through slowly keeps the jelly clear and bright.
Swap the medlar
How well each one fits the dish's main ingredients (lemon, sugar):
- Orangefits better
- Limefits better
- Vanillafits better
- Medlarthe original
Fit is the average pairing score against lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
