Why it works: Beef and pepper are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,971 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Soups and Broths
Ingredients
Directions
Make the stock
Place the shin of beef in a pot with water and bring to a boil.
Reduce heat and simmer for 8 to 10 hours, skimming off any scum that rises.
Strain the broth through a fine sieve into a bowl.
Let the strained broth cool.
Remove the fat from the top of the cooled broth.
Pour the broth through a fine sieve into a saucepan.
Discard the sediment.
Reduce with black pepper
Add 1 oz of whole black pepper.
Boil briskly, skimming off any scum.
Reduce the broth until it thickens to about 1 quart.
Transfer the reduced broth to a smaller saucepan.
Simmer gently until it reaches a syrup-like consistency.
Test a small amount in a saucer; if it sets like jelly, it is done.
Store
Pour the finished broth into small pots.
Store in a dry place, covered tightly.

What each ingredient does
- Shin of beef
- Long simmering releases gelatin and flavour from the bone and connective tissue, giving the broth body.
- Whole black pepper
- Provides the aromatic, pungent flavour that defines the finished broth.
The step that matters
Reducing to a syrup-like consistency. Reducing concentrates the gelatin and flavour, so the broth sets like jelly when cooled. Reducing too little leaves it thin, while reducing too far can make it overly concentrated or stick and scorch on the pan bottom.
