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 ↓
Caramel Sugar for Puddings
Ingredients
Directions
Prepare
Combine the broken sugar with just enough water to soak it in a copper sugar boiler.
Dissolve the sugar.
Prepare a small basin of water with ice and have half a lemon and an iron spoon ready.
Cook and test
Place the mixture on a quick fire with a cover and boil rapidly.
As the sugar reduces, dip the spoon handle into the sugar.
Dip the spoon handle into the ice water to test.
When it breaks with a snap between your fingers, add the lemon juice.
Test again quickly.
Remove from the fire.

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.

Shared aroma: 2-nonenal (fatty, green).
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
- Sugar
- Forms the caramel base, and its cooking stage determines the final texture and colour.
- Lemon juice
- Adds acidity that helps prevent the sugar from crystallising.
The step that matters
Testing the sugar stage with the ice water. Sugar darkens and sets quickly as it approaches the target stage. Testing in ice water shows whether it has reached the brittle snap stage, and testing again quickly prevents overcooking, which can make it bitter.
