Why it works: Beef and mutton are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,373 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Bone Stock
Ingredients
Directions
Start the stock
Place the bones in a large pot and cover them with cold water.
Bring the water to a boil, then reduce to a gentle simmer.
Simmer and top up
Simmer the stock all day, adding more water as needed to maintain the liquid level.
Add any surplus bones each day to avoid waste.
Finish and clean up
Remove bones when they appear dull and have released their gelatin.
Clear the stock pot of old bones at least once a week in cold weather.

What each ingredient does
- Bones
- Release gelatin, collagen and minerals that give the stock body and savory flavor.
- Cold water
- Acts as the medium that slowly draws flavor and gelatin out of the bones.
The step that matters
Bring to a boil, then reduce to a gentle simmer. Vigorous boiling emulsifies fat and fine particles into the liquid, making the stock cloudy and greasy. A gentle simmer extracts flavor and gelatin while keeping the stock clearer.
