Why it works: Arrowroot and lemon match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 553 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Bisque of Lobster
Ingredients
Directions
Prepare the lobster
Remove the flesh from the lobster and cut it into small dice. Set aside.
Combine the washed claws and shells with the fish stock and seasoning.
Make the stock

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lobster
- Provides the sweet, rich meat and shell flavor that defines the bisque.
- Fish stock
- Forms the liquid base and carries the flavor of the shells.
- Milk and cream
- Adds richness and a smooth, velvety body to the soup.
- Arrowroot
- Thickens the stock so the soup has body without becoming cloudy or pasty.
- Lobster spawn
- Adds color and a rich, concentrated lobster flavor to the soup.
The step that matters
Thicken the strained stock with arrowroot. Arrowroot thickens best when the liquid is hot and gently simmering, and it loses thickening power if boiled for long. Adding it to stock that is too cool or overheated can leave lumps or a thin result.
Swap the arrowroot
How well each one fits the dish's main ingredients (lobster, fish, milk, cream, lemon):
