Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Baked Hash
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the mixture
Chop the cold cooked beef or veal and cold potatoes very fine.
Add salt, pepper, butter, and bread crumbs to taste.
Season with minced onion and parsley.
Beat the egg with the milk and add to the mixture.
Bake and serve
Sprinkle bread crumbs over the top.
Lay the strip of breakfast bacon on it.
Bake at 400°F (200°C) until brown.
Fold like an omelet.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the chopped meat and potato together so the hash holds its shape.
- Milk
- Adds moisture that keeps the baked mixture from drying out.
- Bread crumbs
- Absorb moisture and add body, and help the top brown in the oven.
- Cold potatoes
- Provide the bulk and starch that give the hash its soft, hearty texture.
- Cold cooked beef or veal
- Supplies the main meaty flavour and substance of the dish.
The step that matters
Bake at 400°F (200°C) until brown. The egg and milk set as they heat, so the mixture firms up; underbaking leaves it loose and wet, while overbaking dries it out. Browning depends on surface heat and the bread crumbs.
Swap the onion

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