Why it works: Parsley and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Lobster Paul Bert
Ingredients
Directions
Poach the lobsters
Place lobsters in boiling water with parsley, sliced onions, salt, pepper, and vinegar.
Boil steadily for twenty minutes, then remove.
Detach the bodies from the tails.
Remove the meat from the shells by breaking the inside of the shell only.
Wash and dry the shells.
Cut the tail meat into transversal slices.
Make the filling
Put four ounces of butter into a sautoir, arrange the lobster escalops on top, and sauté them.
Add a small finely chopped shallot, shrimps, and walnuts.
Drain off the butter.
Replace it with a reduced béchamel sauce thickened with egg yolks, cream, and fresh butter, with lemon juice and chopped parsley, ensuring the sauce is quite thick.
Serve
Fill the lobster shells with the preparation.
Dress them crown-shaped on a bed of parsley.
Arrange a bunch of parsley leaves on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lobsters
- Provide the main meat, which is cooked and cut into slices for the filling.
- Egg yolks
- Thicken the béchamel sauce into a rich, spoonable texture.
- Cream
- Adds richness and smoothness to the thickened sauce.
- Butter
- Adds fat and flavour, enriching the sauté and the sauce.
- Walnuts
- Add texture and a nutty flavour to the filling.
The step that matters
Thickening the sauce. Egg yolks set when heated, so the sauce must be kept gently warm and not boiled, or it can curdle and turn grainy instead of thick and smooth.
Swap the onion
How well each one fits the dish's main ingredients (lobster, parsley, pepper, vinegar, butter, shallot, shrimp):
- Chivefits better
- Mustardfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against lobster, parsley, pepper, vinegar, butter, shallot, shrimp. Candidates are from the same food group and used in at least 100 recipes.
