Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Boiled Shoulder of Mutton with Onions
Ingredients
Directions
Boil the mutton
Put the shoulder of mutton in a two-gallon pot with a handful of salt and plenty of water.
Allow it to boil gently for about two hours.
When done, place the shoulder on its dish.
Make the onion sauce
Chop six or eight large onions.
Boil the onions with a pint of water for twenty minutes, until the water is reduced to half a pint.
Add two ounces of butter, a pint of milk, four ounces of flour, pepper, and salt to the onions.
Stir the sauce while boiling for ten minutes.
Smother the shoulder with the following sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk and butter into a smooth, coating sauce.
- Butter
- Adds richness and fat to the sauce, giving it a smoother mouthfeel.
- Milk
- Forms the liquid base of the sauce, adding creaminess and body.
- Onions
- Give the sauce its sweetness and savory aroma as they soften in water.
The step that matters
Stir the sauce while boiling for ten minutes. Flour thickens sauces only when stirred during boiling; without constant stirring it can clump on the bottom of the pot and scorch, leaving lumps and a burnt taste.
