Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lobster meat
Provides the main flavour and sweet seafood character of the soup.
Cream
Adds richness and a smooth, velvety body to the soup.
Milk
Thins the cream and adds mild sweetness and liquid body.
Flour
Thickens the liquid as it heats, giving the soup body.
Butter
Adds fat and a glossy, rich mouthfeel when stirred in at the end.

The step that matters

Adding the flour slurry. Flour must be mixed smooth in cold milk first; dumped in dry or added unmixed, it clumps and cannot thicken the soup evenly.
