Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Ox Heart, Baked
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
Wash the heart in several waters.
Cut away the lobes and soak it in vinegar and water for three hours.
Drain and slice the heart into thin steaks lengthwise.
Layer and bake
Grease a pie dish and layer sliced potatoes at the bottom.
Add 2-3 rashers of bacon on top of the potatoes.
Layer the heart slices, followed by more bacon and then more potatoes, repeating until the dish is full.
Dredge pepper over each layer and add salt if needed, depending on the bacon's quality.
Pour ½ pint of water over the entire dish.
Bake in a moderate oven at 350°F (175°C) for one and a half hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox heart
- Forms the main meat, becoming tender and savoury as it bakes slowly in liquid.
- Vinegar
- Soaked with the heart beforehand, its acidity helps tenderise and freshen the meat.
- Potatoes
- Form a starchy base layer that absorbs juices and soaks up flavour as the dish bakes.
- Bacon
- Its fat bastes the layers and adds savoury flavour as it renders during baking.
The step that matters
Soaking the heart in vinegar and water. Ox heart is dense and can be tough. Soaking in an acidic liquid helps loosen its muscle fibres, so the slices turn tender rather than chewy after baking.
Swap the potato
How well each one fits the dish's main ingredients (vinegar, pepper):
- Capsicumfits better
- Mustardfits better
- Cabbagefits better
- Potatothe original
Fit is the average pairing score against vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
