Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef Loaf
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
Preheat your oven to 350°F (175°C).
Make and bake the loaf
In a large bowl, combine the round steak, lean pork, rolled crackers, beaten eggs, salt, and pepper.
If desired, add chopped onion to the mixture.
Shape the mixture into a loaf and place it in a baking dish.
Bake for 1.5 hours or until cooked through.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Forms the bulk of the loaf and gives it a meaty, sliceable body.
- Lean pork
- Adds a little extra fat and tenderness to the mixture.
- Crackers
- Absorb moisture and help the loaf hold its shape while baking.
- Eggs
- Bind the mixture together so it sets firmly when baked.
The step that matters
Shape the mixture into a loaf. The mixture should be packed evenly without being overworked. Loose packing lets the loaf crumble when sliced, while overworking makes the texture dense and tough.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (pork, egg, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against pork, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
