Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Stuffed Tomatoes
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Cut the tops off the tomatoes and scoop out the insides carefully.
Set the scooped-out tomato flesh aside for sauce.
Stuff and bake
In a bowl, mix the eggs, parsley, butter, onion, breadcrumbs, pepper, and salt thoroughly.
Stuff each tomato with the mixture and place them in a buttered baking dish.
Bake for 1 hour.
Serve with brown gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the filling together so it holds its shape when baked.
- Breadcrumbs
- Absorb moisture and give the filling body and a soft texture.
- Butter
- Adds richness and fat, keeping the filling tender and flavorful.
- Onion
- Adds aromatic flavor and moisture to the filling.
The step that matters
Scooping the tomatoes. Scoop carefully so the tomato shells stay intact; a torn shell cannot hold the filling and may collapse in the oven.
Swap the onion
How well each one fits the dish's main ingredients (egg, parsley, butter, pepper):
- Shallotfits better
- Chivefits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against egg, parsley, butter, pepper. 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.
