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 ↓
Punch Jelly
Ingredients
Directions
Make the jelly
In a saucepan, combine all ingredients except the whisky.
Cut the yellow part of the lemon rinds as finely as possible.
Stir the mixture until it boils, then cover and let it stand for 10 minutes.
Pass through a jelly bag with 1 quart of boiling water.
Layer the mold
Add the jelly and slightly warmed whisky.
Pour 1 inch of jelly into a mold and let it nearly set.
Garnish with small quarters of peeled and cut lemon.
Continue layering with cold jelly and lemon until the mold is full.
Unmold
Once firm, dip the mold in warm water and turn out quickly.

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
- Irish whisky
- Provides the main flavour and alcohol base of the jelly.
- Leaf gelatine
- Sets the liquid so the jelly holds its shape when turned out.
- Egg whites and shells
- Bind to impurities as they heat, clarifying the jelly to a clear look.
- Lump sugar
- Adds sweetness and balances the alcohol and lemon.
- Lemon juice
- Adds acidity that brightens the flavour of the jelly.
The step that matters
Let the layer nearly set before adding the next. If the layer is still too liquid, the new layer mixes into it and the stripes blur. If it is fully set, the layers will not bond and may separate when cut.
Swap the lemon
How well each one fits the dish's main ingredients (whisky, sugar, egg):
- Vanillafits better
- Applefits better
- Raisinfits better
- Lemonthe original
Fit is the average pairing score against whisky, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
