Why it works: Egg and roe work together. They rank in the top 14% of all ingredient pairs, and cooks put them together in 243 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓
Potted Prawns
Ingredients
Directions
Make the butter
Let the cooked prawn meat cool.
Mix the cooked prawn meat with iced butter in equal parts.
Pound the mixture thoroughly until no granulated particles remain.
Flavor and finish
Add 2 anchovies for flavor to make crab‑coral butter.
For lobster butter, wash the lobster meat to remove juices, then dry and pound it.
Optionally, pass hard‑boiled yolks through a sieve to tint the butter yellow.
Flavor with soft herring roes or cod's roes, pepper, and capers if desired.
Soak very salty fish in water before use; anchovies in oil do not need soaking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked prawn meat
- Provides the main shellfish flavour and the solid body of the butter.
- Iced butter
- Supplies the fat that firms when chilled and blends smoothly with the pounded meat.
- Anchovies
- Add savoury depth and a salty, umami note to the butter.
The step that matters
Pound the mixture thoroughly. Pounding until no granules remain breaks the meat into fine particles and blends it evenly into the fat. Leftover gritty bits leave the butter with an uneven, sandy texture.
Swap the capers
The recipe marks capers as optional. How well each one fits the dish's main ingredients (meat, butter, egg, roe):
- Nutmegfits about as well
- Parsleyfits about as well
- Capersthe original
- Thymefits less well
Fit is the average pairing score against meat, butter, egg, roe. Candidates are from the same food group and used in at least 100 recipes.
