Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Bisque of Lobster
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the stock
Chop the lobster meat finely and place it in a saucepan with half of the white stock.
Pound the lobster coral with half of the butter and add it to the stock.
Tie the onion, mace, parsley, and bay leaf in a small bag and add to the stock; simmer for 1 hour.
In a double boiler, combine the remaining stock and bread; simmer for 30 minutes.
Scald the cream.
Strain all the stock through a fine sieve.
Finish the bisque
Cook the remaining flour and butter until smooth, then add the strained mixture and seasoning.
Strain again, add the cream and bits of lobster meat, and do not boil after adding the cream.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lobster
- Provides the main sweet, briny flavour and the tender meat that gives the bisque body.
- Lobster coral
- Adds colour and a rich, concentrated lobster flavour when pounded into the stock.
- White bread crumbs
- Thicken the stock slightly, giving it more body and a smoother mouthfeel.
- Cream
- Adds richness and a smooth, velvety texture to the finished soup.
- Butter
- Adds fat and flavour, and is cooked with flour to form a thickening roux.
- Flour
- Thickens the bisque when cooked with butter into a roux.
The step that matters
Do not boil after adding the cream. Boiling cream can cause it to separate and curdle, leaving the bisque grainy and thin instead of smooth and velvety.
Swap the onion
How well each one fits the dish's main ingredients (lobster, bread, cream, flour, celery, butter, parsley):
- Leekfits better
