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 ↓
Candied Orange, or Lemon Peels
Ingredients
Directions
The book says “a slow oven”. The 300°F in the steps is the modern equivalent, not the book's own figure.
Prepare the peels
Clean the lemon or orange peels, removing all pulp.
Soak the peels in salt and water for 2 days.
Scald and drain the peels until dry.
Candy the peels
Boil the peels in a thin syrup until they look clear.
Transfer the peels to a thick syrup made with fine loaf sugar.
Simmer until the sugar candies around the peels.
Dry and finish
Lay the peels separately on a wire rack to drain.
Sprinkle sifted sugar over the peels and dry them in a cool oven (300°F / 150°C).

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).
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
- Lemon or orange peels
- Provide the main flavour and the candied body once sugar penetrates them.
- Fine loaf sugar
- Sweetens and, in thick syrup, replaces the water in the peel, preserving it as candy.
The step that matters
Simmering in the thick syrup until the sugar candies around the peels. Sugar must slowly replace the water inside the peel. If the syrup is boiled too hard or too briefly, the peel stays tough or the sugar crystallises unevenly on the surface instead of soaking in.
