Why it works: Shallot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Mushroom Tartlets, with Cream
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the shells
Butter and flour the tartlet moulds, then line them with a thin layer of puff pastry.
Make the filling
In a frying pan, melt the butter and sauté the shallots until soft.
Add the sliced mushrooms and cook over high heat for a few minutes.
Season with salt, pepper, and parsley, then fill the tartlet moulds with the mixture.
Bake and serve
Bake in a 400°F (200°C) oven until nearly done.
Beat the egg whites until frothy and mix in the cold cream sauce.
Pour a little of the mixture over each tartlet and return to the oven.
Bake until browned, then remove from the moulds and serve on a napkin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main savoury filling and moisture that cooks down in the tartlets.
- Puff pastry
- Forms the flaky, crisp shell that holds the filling.
- Egg whites
- Beaten and mixed into the cream, they help the topping set and puff lightly when baked.
- Reduced cream sauce
- Adds richness and moisture, giving the topping a creamy, custard-like body.
- Butter
- Adds fat and flavour for sautéing the shallots and mushrooms and helps browning.
The step that matters
Bake until nearly done before adding the topping. Partly baking the pastry first sets its structure and keeps it crisp, so the wet egg and cream topping does not soak the base and make it soggy.
Swap the parsley
How well each one fits the dish's main ingredients (mushroom, butter, shallot, pepper, egg, cream, sauce):
- Capersfits about as well
- Tarragonfits about as well
- Parsleythe original
- Nutmegfits about as well
Fit is the average pairing score against mushroom, butter, shallot, pepper, egg, cream, sauce. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
