Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Lobster Bisque
Ingredients
Directions
Prepare
Split the lobster down the back and remove the meat.
Break the claws and pound the shells in a mortar until fine.
Make the bisque
Mix the pounded shells with the butter in a stewpan and heat until hot.
Add the flour and cook for 10 minutes.
Moisten with the wine and fish stock, then add the vegetables, bouquet garni, and peppercorns.
Stir until it boils, then reduce heat and simmer for 20 minutes.
If too thick, add more stock.
Strain through a tammy cloth.
Finish and serve
Cut the claw meat into neat dice and place in a soup tureen with the cream.
Heat the bisque, season with salt, lemon juice, and cayenne, then pour into the tureen and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lobster shells
- Provide the concentrated shellfish flavour that gives the bisque its character.
- Butter
- Carries the shell flavour and adds richness to the base.
- Flour
- Thickens the bisque as it cooks with the butter and liquid.
- White wine
- Adds acidity and aroma that brighten the rich stock.
- Cream
- Adds smoothness and richness to the finished soup.
- Fish stock
- Forms the liquid base that the bisque simmers in.
The step that matters
Adding the flour and cooking it for 10 minutes. The flour must cook in the hot butter long enough to lose its raw taste and thicken evenly; undercooked flour leaves a pasty flavour and lumps, while the later stock addition should be done gradually to avoid clumping.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
