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 ↓
Calfs-foot Broth
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Split the calf's foot and place it in a fire-proof jar with all ingredients.
Bake
Tie down the jar and bake in a slow oven at 300°F (150°C) for eight hours.
Strain and chill
Strain the mixture through a sieve into a basin and let it cool.
Remove the fat from the top when cold.
Serve
Heat the broth when required for use.

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
- Calf's foot
- Releases gelatin into the liquid, giving the broth body and a jelly-like set when cold.
- New milk
- Adds richness and softness, rounding out the flavour of the long-simmered broth.
- Sugar
- Adds sweetness and helps balance the savoury, mineral taste of the broth.
The step that matters
Remove the fat from the top when cold. Fat rises and solidifies on top as the broth cools. Skimming it while cold leaves a cleaner, lighter broth, because warm fat would otherwise remain mixed into the liquid.
