Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stewed Ox Cheeks
Ingredients
Directions
The book says “a moderate oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Soak the ox cheeks in salt and water for half an hour.
Wash the cheeks thoroughly in five or six changes of water.
Stew and finish
Brown the cheeks in a pan with onions and a little sugar.
Cover the cheeks with boiling water and let them simmer gently for five hours.
For the last hour, cover the pan with a lid and place it in a 300°F (150°C) oven to reduce the gravy.
Season with pepper and salt to taste before serving.

Sugar and pepper barely smell alike, yet cooks put them together in 19,401 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
- Ox cheeks
- Long, gentle simmering breaks down the tough connective tissue, leaving the meat tender.
- Onions
- Release sugars and aroma as they cook, adding sweetness and depth to the gravy.
- Sugar
- Caramelises during browning, helping the cheeks and onions develop a richer colour and flavour.
The step that matters
Browning the cheeks. Browning creates deep flavour through the Maillard reaction. The cheeks must be dried and cooked in a pan with enough room, otherwise they steam instead of browning and the gravy tastes flat.
Swap the onion
How well each one fits the dish's main ingredients (sugar, pepper):
- Capsicumfits better
- Mustardfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
