Why it works: Egg and brandy are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 7,340 recipes. Both carry acetoin, which smells butter, cream. The science ↓
Lemon Jelly
Ingredients
Directions
Prepare the gelatine
Soak gelatine in ½ pint of water for 30 minutes.
Make the jelly
In a saucepan, combine 1½ pints of water with lemon peel and juice; bring to a boil.
Pour boiling water over the soaked gelatine and sweeten with saccharin.
Return to saucepan, stir in beaten egg white and shell, and bring to a boil.
Boil for 1 minute, then remove from heat and let stand for 2 minutes.
Skim and strain through a jelly bag until clear.
Add brandy and pour into a jelly mold to set.

Lemon and egg barely smell alike, yet cooks put them together in 44,316 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
- Gelatine
- Sets the liquid into a firm, wobbly jelly as it cools.
- Egg white and shell
- When heated, the egg white coagulates and traps impurities, clarifying the liquid.
- Lemon
- Supplies the peel and juice that give the jelly its bright, sharp flavour.
- Brandy
- Adds aroma and flavour to the finished jelly.
The step that matters
Straining through a jelly bag until clear. Clarity depends on the egg white having coagulated and trapped particles during boiling. Rushing the straining or disturbing the bag lets cloudy sediment pass through, leaving the jelly murky instead of sparkling.
Swap the lemon
How well each one fits the dish's main ingredients (egg, brandy):
- Currantfits better
- Vanillafits better
- Apricotfits better
- Lemonthe original
Fit is the average pairing score against egg, brandy. Candidates are from the same food group and used in at least 100 recipes.
