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

What each ingredient does

Lobster
Main protein; cooking sets its flesh firm and opaque.
Butter
Adds fat and richness and helps the surface brown.
Flour
Mixed with butter, it helps the basting coat form a froth and brown.

The step that matters

Basting until it has a fine froth. Butter and flour coat the shell, and as it heats they foam and brown. Skimping on basting leaves the surface pale and dry rather than golden and crisp.

Swap the lemon
