Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 27,039 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
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 heart
Stuff the calf's heart with forced meat, cover with butter, and dredge with flour.
Place in an earthen dish with a little water and bake at 350°F (175°C).
Make the sauce
Boil half the liver and all the offal together for 30 minutes, then chop finely.
In a pan, combine the chopped liver and offal with gravy, lemon pickle, catsup, lemon juice, pepper, and salt.
Thicken the mixture with butter rolled in flour.
Serve
To serve, pour the minced meat into a dish, place the fried liver slices and bacon on top, and set the heart in the center.

Butter and flour share little aroma chemistry, yet 122,858 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's heart
- Forms the main body of the dish, cooked whole so it stays moist and tender inside.
- Forced meat
- Stuffing that fills the heart and adds richness and moisture as it cooks.
- Butter
- Enriches the coating and, rolled with flour, thickens the sauce and adds richness.
- Flour
- Dredged over the butter and used to thicken the sauce, giving body and a light browning.
- Liver
- Provides the rich, savoury flavour of the minced sauce and the fried slices served on top.
The step that matters
Thicken the mixture with butter rolled in flour. Adding the flour-butter mixture to hot liquid without enough stirring can form lumps, so it should be whisked in gradually while the sauce simmers to become smooth and evenly thickened.
