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 ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Grind or chop the round steak and beef suet.
Add salt, pepper, eggs, chopped onion, bread or cracker crumbs, and milk. Mix thoroughly and shape into two loaves.
Roll the loaves in bread crumbs.
Bake
Dot with bits of butter.
Bake at 400°F (200°C) for 1 hour, basting often.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Provides the main meaty body and structure of the loaf.
- Beef suet
- Adds fat that keeps the loaf moist and tender as it bakes.
- Eggs
- Bind the mixture so the loaves hold their shape when sliced.
- Bread or cracker crumbs
- Soak up milk and juices, helping the loaf stay moist and firm.
- Milk
- Adds moisture that keeps the meat tender during baking.
The step that matters
Shaping and mixing the loaves. Mixing thoroughly spreads the eggs and crumbs evenly so the loaves bind together. Overworking packed meat can make it dense and tough, so shape gently.
Swap the onion
