Why it works: Milk and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 77,875 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
In a saucepan, combine the milk and sugar.
Heat over low to medium heat, stirring until the sugar dissolves.
Increase the heat and bring the mixture to a gentle boil.
Reduce the heat and simmer until the mixture thickens, about 30-40 minutes.
Remove from heat and let cool before storing in a sealed container.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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).
Milk and sugar barely smell alike, yet cooks put them together in 77,875 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
- Whole milk
- Provides the liquid and milk solids that thicken and brown as the mixture reduces.
- Granulated sugar
- Adds sweetness and, with the reduced liquid, gives the mixture its thick, syrupy body.
The step that matters
Simmering until thickened. Simmering must be gentle and steady. Too high a heat can scorch the milk sugars and milk solids on the pan bottom, and the mixture keeps thickening as it cools, so stopping too early leaves it thin.
