Why it works: Beef and pork match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,690 recipes. Both carry 12-methyltridecanal, which smells tallowy, beefy. The science ↓
Meat 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 the oven to 350°F (175°C).
Chop the beef, pork, and onion finely.
Season the meat mixture with salt, pepper, and sage.
Soak the bread in water until soft, then press out the water.
Shape and bake
Add the soaked bread and eggs to the meat mixture and combine well.
Shape the mixture into a loaf and place it in a baking dish.
Bake for 3 hours, basting often.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main meaty structure and rich flavor of the loaf.
- Fresh pork
- Adds fat, which keeps the loaf moist and tender as it cooks.
- Eggs
- Bind the meat and bread together so the loaf holds its shape when sliced.
- Flour bread
- Soaked and squeezed, it adds moisture and softness that keeps the meat from drying out.
- Onion
- Adds sweetness and aroma as it cooks into the meat.
The step that matters
Bake for 3 hours, basting often. Long baking at moderate heat cooks the meat through and gives a tender loaf, but it can dry out on the surface. Basting adds moisture and helps keep the exterior juicy and browned.

Fit is the average pairing score against beef, pork, pepper, sage, flour, bread, egg. Candidates are from the same food group and used in at least 100 recipes.
