Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef Loaf, Onion Sauce
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the loaf
Preheat the oven to 350°F (175°C).
In a bowl, mix the minced beef, butter, beef stock or milk, beaten eggs, salt, pepper, nutmeg, and rolled crackers until well combined.
Form the mixture into an oblong loaf.
Place the loaf in a granite pan.
Bake and baste
Bake the loaf.
Baste the loaf with a mixture of butter and water until nearly done.
Make the onion sauce and finish
Brown the chopped onion in 2 tablespoons of butter.
Add the flour and cook until golden.
Stir in the soup stock or meat gravy, salt, mustard, and lemon peel.
Boil for 2-3 minutes.
Pour the onion sauce over the loaf.
Bake for an additional 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold beef
- Forms the body of the loaf and gives it its meaty structure.
- Eggs
- Bind the mixture and set when baked, holding the loaf together.
- Crackers
- Absorb liquid and add body, helping the loaf hold its shape.
- Beef stock or milk
- Adds moisture so the loaf stays tender rather than dry.
- Flour
- Thickens the onion sauce once cooked in butter until golden.
The step that matters
Browning the flour in the onion butter. Cooking flour in fat until golden removes raw starch taste and thickens the sauce evenly. Stopping too early leaves a pasty flavour; cooking too long darkens it and weakens its thickening power.
Swap the onion
