Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef's Heart, Stuffed
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the heart
Trim and clean the heart.
Sprinkle salt over it and let it stand for 2–3 hours, changing the water 2–3 times.
Wipe the heart dry.
Stuff and bake
Fill the cavities with a dressing of bread crumbs, pepper, salt, and chopped onion.
Add enough butter to the mixture to make the crumbs adhere together.
Place the stuffed heart in a 350 °F (175 °C) oven and bake for 15 minutes per pound.
For better flavor, roast it before the fire if possible.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef heart
- Forms the main body of the dish and is the meat that is stuffed and baked.
- Bread crumbs
- Absorb the seasonings and form the dressing that fills the cavities.
- Butter
- Binds the crumbs together so the dressing holds its shape and adds richness.
- Onion
- Adds aromatic flavor to the dressing.
The step that matters
Soak and dry the heart before stuffing. Soaking in changed water draws out blood and impurities, which keeps the meat clean-tasting. Wiping it dry before stuffing matters because surface moisture would keep the dressing from sticking and could steam the meat rather than letting it brown.
Swap the onion
How well each one fits the dish's main ingredients (beef, bread, pepper, butter):

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