Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stuffed Heart
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the stuffing
Soak stale bread in cold water until soft, then wring it dry in a clean towel.
Peel and chop the onion, then fry it in butter until light yellow.
Add the soaked bread, salt, pepper and powdered herbs to the onion.
Stir the mixture until scalding hot.
Stuff and bake
Wash the heart in cold water.
Stuff the heart with the mixture and sew it up.
Place the heart on a baking pan with pared and washed potatoes.
Bake in a 400°F (200°C) oven for one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef's heart
- Forms the main body of the dish and holds the stuffing while it cooks.
- Stale bread
- Soaked and wrung dry, it absorbs moisture and gives the stuffing body.
- Butter
- Fat for frying the onion, adding richness and flavor to the stuffing.
- Onion
- Frying softens it and builds a sweet, savory aroma in the stuffing.
- Potatoes
- Bake alongside the heart, absorbing drippings and becoming tender.
The step that matters
Wring the bread dry. Bread soaked in water holds excess moisture. If it is not squeezed dry, the stuffing stays wet and loose and can make the heart cook unevenly.
