Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare the lobster as for casseroles.
Remove the tail from the shell and cut it into slices thicker than a coin.
Heat the lobster slices in butter until lightly browned.
Arrange the slices in a crown shape on a plate, alternating with fried croutons of the same size.
In a saucepan, melt butter and mix with flour until well combined.
Add water, season with salt and pepper, and bring to a boil.
Add fish quenelles, oysters, and blanched mushrooms to the sauce.
Thicken the sauce with one or two egg yolks and pour it in the center of the lobster crown.
