Why it works: White pepper and pepper are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 1,478 recipes. Both carry piperonal, which smells bitter, coconut. The science ↓
Potted Kipper
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Pour water over the kippers and place them in a fireproof dish.
Bake in the hot oven for eight minutes.
Carefully lift the kippers onto a large dish.
Make the paste
Scoop the oil from the top of the kippers and set it aside.
Remove as many bones as possible from the kippers and add the fish to the oil.
Add a dash of white and black pepper and a good amount of butter.
Pound the mixture into a paste.
Jar and set
Transfer the paste into small jars and let it cool.
Spread a little cold butter on top to exclude air.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kippers
- Provide the main flesh and rich smoky flavour of the paste.
- Butter
- Adds fat and richness, giving the paste a smooth, spreadable texture.
- Oil from the tin
- Adds moisture and fat, helping the fish blend into a smooth paste.
The step that matters
Remove as many bones as possible from the kippers. Kipper bones are fine and hard to see once the fish is cooked and flaked. Any left in the paste can be unpleasant to bite into, so checking carefully before pounding matters.
Swap the white pepper
How well each one fits the dish's main ingredients (pepper, butter):
- Parsleyfits better
- Sagefits better

- White pepperthe original
Fit is the average pairing score against pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
