Why it works: Sage and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 5,388 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

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).

Bake

  1. Mix all ingredients together evenly to form a loaf.

  2. Place the loaf in a long baking tin.

  3. Bake for 1½ hours.

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

What each ingredient does

Hamburger steak
Provides the main body and fat that give the loaf its meaty texture and flavour.
Egg
Binds the mixture so the loaf holds its shape when sliced.
Bread crumbs
Absorb the milk and juices, keeping the loaf moist and tender.
Milk
Adds moisture that softens the crumbs and keeps the meat tender as it bakes.
Onion
Adds moisture and savoury sweetness as it softens during baking.

The step that matters

Mix all ingredients together evenly to form a loaf.. Overmixing works the meat proteins into a dense, rubbery texture, while uneven mixing leaves pockets of seasoning and binder. Mix just until combined so the loaf stays tender and seasoned throughout.

Swap the onion

How well each one fits the dish's main ingredients (milk, egg, bread, sage, pepper):

  1. Capsicumfits better
  2. Sweet potatofits better
  3. Spinachfits better
  4. Onionthe original

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