Why it works: Shallot and mushroom 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 ↓
Stuffed Tomatoes, Cardinal Style
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Prepare the tomatoes as in the previous recipe.
In a saucepan, combine the shallots and butter.
Cover and cook on low heat until soft but not browned.
Add the chopped tomatoes and mushrooms.
Cook until the moisture is reduced.
Stir in the reduced Allemande sauce, bread crumbs, salt, and pepper. Mix well.
Add the yolks of the raw eggs. Mix until combined.
Stuff and bake
Stuff the tomatoes with the mixture.
Sprinkle with bread crumbs.
Arrange the stuffed tomatoes in a flat saucepan.
Drizzle with sweet oil.
Bake in a preheated oven at 400°F (200°C) until browned.
Serve with a puree of tomatoes around the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Release moisture as they cook down, which is reduced to concentrate the filling.
- Butter
- Fat that softens the shallots gently and adds richness to the filling.
- Eggs yolks
- Bind the filling so it holds its shape when stuffed and baked.
- Reduced allemande sauce
- Adds body and a rich, creamy flavour to the filling.
- Bread crumbs
- Absorb moisture and add texture to the filling and the browned topping.
The step that matters
Cook until the moisture is reduced. Tomatoes and mushrooms release a lot of water. If it is not cooked off, the filling stays loose, won't bind with the egg yolks, and can make the stuffed tomatoes soggy in the oven.
