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 ↓
Calf’s 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 fireproof jar.
Add new milk, water, salt, and sugar to the jar.
Bake
Tie down the jar and bake in a slow oven at 300°F (150°C) for eight hours.
Strain and skim
Strain the broth through a sieve into a basin and let it cool.
Remove the fat from the cooled broth.

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
- Provides gelatin and body, so the broth sets and feels rich.
- New milk
- Adds richness and a soft, creamy mouthfeel to the broth.
- Water
- Extracts flavour and collagen from the foot over the long bake.
The step that matters
Bake in a slow oven for eight hours. A low, steady heat lets collagen in the foot break down into gelatin slowly. Higher heat would reduce the liquid quickly and could scorch the milk, so the jar must stay sealed and the temperature low.
