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 by removing the tops and scooping out the insides.
In a saucepan, melt the butter and cook the shallots on low heat until soft, without browning.
Add the chopped tomatoes and mushrooms, cooking until the moisture is reduced.
Stir in the reduced Allemande sauce, bread crumbs, salt, and pepper.
Remove from heat and mix in the yolks of the eggs.
Stuff and bake
Stuff the prepared tomatoes with the mixture and sprinkle with additional bread crumbs.
Arrange the stuffed tomatoes in a flat baking dish and 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
- Eggs
- Yolks bind the filling and help it set lightly when baked.
- Butter
- Fat that softens the shallots and adds richness to the filling.
- Mushrooms
- Release moisture as they cook, adding earthy flavor and body to the filling.
- Reduced allemande sauce
- Adds a rich, creamy body and savory flavor to the filling.
- Bread crumbs
- Absorb moisture and give the filling structure and a browned topping.
The step that matters
Cook the shallots gently without browning. Low heat softens the shallots and builds sweetness without bitterness. Browning them would add harsh flavor and alter the delicate filling.
