Why it works: Mushroom and shallot are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,982 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Mushroom Tart and Gravy
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the pastry
Pick and wash the mushrooms, remove the stalks, dry them, and cut them into pieces.
Make pastry with the wheatmeal, 3 oz of butter, and a little cold water.
Roll the pastry out and line a large plate.
Assemble the tart
Heap the mushrooms on the pastry.
Dredge the mushrooms well with pepper and salt.
Scatter the remaining butter in bits over the mushrooms.
Keep a little of the pastry to cut into thin strips.
Lay the strips in a diamond shape across the pie.
Bake the pie for 2 hours in a moderate oven at 350°F (175°C).
Make the gravy
For the gravy, fry the stalks and shallots in the butter.
Gently cook them in ½ pint of water for 1 hour, adding seasoning and bay leaves.
Strain the sauce.
Return it to the saucepan.
Thicken it with the cornflour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wheatmeal
- Forms the pastry structure that holds the mushroom filling.
- Butter
- Adds richness and flakiness to the pastry and enriches the filling and gravy.
- Mushrooms
- Provide the main savoury filling and moisture as they cook.
- Shallots
- Add mild sweetness and aroma to the gravy.
- Cornflour
- Thickens the gravy to a smooth, glossy consistency.
The step that matters
Thicken the gravy after straining. Cornflour thickens only when heated, and it needs to be stirred in while the liquid is simmering, or it stays thin or turns lumpy.
Swap the shallot
How well each one fits the dish's main ingredients (mushroom, butter, pepper):
- Capsicumfits better
- Shallotthe original
- Spinachfits about as well
- Potatofits about as well
Fit is the average pairing score against mushroom, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
