Why it works: Liver and pork are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,606 recipes. Both carry 1-nonanal, which smells fatty, waxy. The science ↓
Calf's Liver
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
Layer diced salt pork in a frying pan.
Add a layer of sliced liver, then another layer of pork, and repeat until all ingredients are used.
Season with coarse sea salt and black pepper.
Pour in boiling water until it just covers the layers.
Bake and serve
Cover the pan tightly and bake at 350°F (175°C) for one hour.
Serve on a hot platter and top with bits of butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Forms the main body of the dish, cooking to a tender texture under moist heat.
- Salt pork
- Releases fat as it bakes, keeping the liver moist and adding savoury flavour.
- Butter
- Adds richness and a silky finish when placed on the hot liver at serving.
The step that matters
Cover the pan tightly and bake. A tight cover traps steam so the liver cooks gently in the boiling water and fat. Overbaking toughens liver proteins and leaves it dry and grainy, so the time and temperature matter.
