Why it works: Pomegranate and lemon match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 225 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Pomegranate Jelly
Ingredients
Directions
Make the syrup
Extract seeds from enough pomegranates to yield 1 pint of syrup.
Clarify the jelly
Combine the syrup, water, lemon juice, lemon rind, sugar, and slightly beaten egg whites in a pan.
Heat gently, whisking until it boils.
When scum rises, remove the whisk and cover the pan.
Let it stand for 10 minutes.
Warm a quart of boiling water in a jelly bag.
Pour the jelly through the warm water until it is clear.
Set and serve
Pour the clear jelly into a copper mold and set aside until firm.
Dip the mold in warm water.
Turn out the jelly quickly.

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
- Pomegranate syrup
- Provides the main flavour and colour of the jelly.
- Egg whites and shells
- Bind impurities into scum when heated, so they can be removed to leave a clear jelly.
- Gelatine
- Sets the liquid into a firm jelly as it cools.
- Lump sugar
- Sweetens the jelly and balances the tartness of the lemon and pomegranate.
- Lemon juice
- Adds acidity that brightens the flavour and balances sweetness.
The step that matters
Pour the jelly through the warm water until it is clear. Egg whites and shells trap cloudy particles as they coagulate, and the jelly must be strained slowly through a warm jelly bag to catch them. If the jelly is poured too fast or the bag is cold, the liquid stays cloudy and the set jelly looks murky.

Fit is the average pairing score against syrup, lemon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
