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 the milk, water, salt, and sugar to the jar.
Bake and strain
Tie down the jar and bake in a slow oven at 300°F (150°C) for eight hours.
Strain the broth through a sieve into a basin and let it cool.
Remove the fat from the cooled broth.
Serve
Serve the broth sweet with sugar and lemon juice or savory with salt and lemon juice.

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 cooled broth sets lightly and feels rich.
- New milk
- Adds fat and richness, softening the flavor of the long-cooked broth.
- Sifted sugar
- Adds sweetness and helps the broth taste rounded when served sweet.
The step that matters
Long, low baking in a sealed jar. Gentle heat over eight hours slowly draws gelatin and flavor from the bone while the sealed lid prevents evaporation and keeps the milk from scorching or curdling into a harsh texture.
