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 ↓

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 the filling
Soak the chopped bread in water and squeeze out the excess.
In a bowl, combine the veal, lean beef, pork, soaked bread, chopped onion, spices, and beaten eggs.
Shape and bake
Form the mixture into a roll.
Bake in a preheated oven at 350°F (175°C) for 1½ hours, basting frequently with beef stock.
Cool and serve
Allow to cool, then slice and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the meat and bread so the roll holds its shape when sliced.
- Bread
- Adds moisture and softness, keeping the meat mixture tender as it bakes.
- Veal
- Provides a mild, delicate meat base with a tender texture.
- Lean beef
- Gives the roll its main meaty flavor and structure.
- Pork
- Adds fat and richness, helping keep the filling juicy.
The step that matters
Basting with beef stock during baking. Frequent basting adds moisture to the surface while the roll cooks, so the outside does not dry out before the centre is fully set.
Swap the onion
How well each one fits the dish's main ingredients (veal, beef, pork, bread, egg):

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