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

  1. Preheat the oven to 350°F (175°C).

Make and bake the loaf

  1. In a large bowl, combine the ground beef, ground salt pork, soaked bread, egg, salt, pepper, and onion if desired.

  2. Mold the mixture into a loaf shape.

  3. Place the loaf in a baking dish and bake for about 45 minutes to 1 hour.

Serve

  1. Serve hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Ground beef
Provides the main body and rich flavor of the loaf.
Ground salt pork
Adds fat that keeps the loaf moist and adds savory richness.
Bread soaked in water
Holds moisture within the meat so the loaf stays tender.
Egg
Binds the mixture so the loaf holds its shape when sliced.

The step that matters

Mold the mixture into a loaf shape. Overworking the meat mixture makes the loaf dense and tough, while a loose shape can crumble. Shape it gently and just enough to hold together.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, pork, bread, egg, pepper):

  1. Capsicumfits better
  2. Potatofits better
  3. Tomatofits better
  4. Onionthe original

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