    Shared aroma: isobutyraldehyde (malty, green).

Butter and flour share little aroma chemistry, yet 124,287 recipes mention both: they likely work on texture and structure more than aroma.

What each ingredient does

Oysters
Provide the main flavor and texture of the sauce.
Butter
Adds richness and carries flavor through the sauce.
Flour
Thickens the liquid into a smooth, coating sauce.
Lemon juice
Adds acidity that brightens the rich oyster flavor.

The step that matters

Add flour and water to thicken. Flour must be fully mixed in before heating so it hydrates evenly; stirred in lumps, it stays grainy and fails to thicken smoothly.
