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

What each ingredient does

Calf brains
Provide a soft, rich base that gives the filling its body and creamy texture.
Oysters
Contribute the briny, savoury flavour that defines the filling.
Butter
Softens the onion and adds richness and a gentle buttery aroma.
Cream
Adds moisture and richness so the filling stays tender and smooth.
Stale bread crumbs
Absorb liquid and help bind the filling into a cohesive mixture.

The step that matters

Scalding the oysters until the edges curl. Brief heat firms the oysters enough to cut cleanly and releases their liquor, while overcooking makes them tough and rubbery, so they should be removed as soon as the edges curl.

Swap the onion

How well each one fits the dish's main ingredients (oyster, butter, parsley, celery, pepper, cream, bread):
