Why it works: Mushroom and lobster work together. They rank in the top 13% of all ingredient pairs, and 178 recipes mention both. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
The recipe
Ingredients
Contains: milk, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the filling
Sauté the mushroom caps in butter for about 5 minutes, adding the sliced onion if desired.
Cover with seasoned stock and simmer until very tender.
Chop the mixture and press through a sieve; if too moist, reduce to a thick puree.
Add the pounded lobster meat and season with salt, pepper, lemon juice, and tomato ketchup if desired.
Serve
Let cool and use as a filling for sandwiches.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the bulk and earthy flavor of the filling as they soften and break down.
- Butter
- Adds fat and richness while gently browning the mushrooms.
- Stock
- Supplies moisture and savory depth as the mushrooms simmer until tender.
- Lobster meat
- Gives the filling its main sweet, delicate seafood flavor and texture.
The step that matters
Reducing the puree. If the mushroom mixture is still too moist after sieving, it will make the filling watery and soggy in a sandwich. Reducing it to a thick puree concentrates flavor and gives a spreadable texture that holds together.
Flavor stand-ins for the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (mushroom, butter, lobster, meat, pepper, lemon, tomato):

Fit is the average pairing score against mushroom, butter, lobster, meat, pepper, lemon, tomato. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
