Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Heart Fricassee
Ingredients
Directions
Prepare the hearts
Soak the hearts in mild salted cold water until all blood is drawn from them, then cut them into pieces the size of hickory nuts, removing any tough parts.
Make the fricassee
Place the hearts, butter, and diced salt pork in a skillet and allow to simmer and brown, keeping the skillet uncovered.
When browned, add the chopped onion and 2 cups of boiling water, cover, and simmer until the onion is tender.
Mix the flour, salt, and pepper together and add to the mixture, ensuring it doesn't lump, then add the remaining 2 cups of boiling water.
Bake and serve
Pour everything into a baking dish and spread the chopped potatoes over the top.
Bake until the potatoes are tender. Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal hearts
- Form the main body of the dish, becoming tender through slow simmering and baking.
- Butter
- Adds fat for browning the hearts and enriches the flavour of the sauce.
- Salt pork
- Adds fat and savoury flavour as it renders and browns in the skillet.
- Flour
- Thickens the cooking liquid into a smooth, lightly body-rich sauce.
- Potatoes
- Form a starchy layer on top that softens and absorbs moisture as it bakes.
The step that matters
Adding the flour. Flour must be mixed in evenly so it does not form lumps. Lumps stay dry inside the liquid and are hard to smooth out later, so the sauce turns uneven.
Swap the white pepper
How well each one fits the dish's main ingredients (veal, butter, pork, onion, walnut, flour, pepper):
- Sagefits better
- Parsleyfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against veal, butter, pork, onion, walnut, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
