Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomatoes with Walnuts
Ingredients
Directions
Prepare the tomatoes
Take six ripe tomatoes (or one quart of canned ones), plunge them in boiling water, peel, and place in a buttered sauce pan to bake.
When tender, rub through a sieve.
Make the filling
Cut one small onion and cook in two tablespoonfuls of butter until a light brown.
Add the onion to the tomatoes, with one-half cup of finely chopped walnut meats, one-half cup of fine, fresh bread crumbs, and one-fourth cup of grated cheese.
Stir over the fire until all are well blended.
Add two slightly beaten eggs, salt, and pepper; let cook for five minutes.
Serve
Serve hot on rounds of toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and moisture of the dish once softened and sieved.
- Eggs
- Bind the mixture and help it thicken as it cooks.
- Walnut meats
- Add crunch and rich, nutty texture against the soft tomato base.
- Grated cheese
- Adds savory flavor and helps the mixture become rich and cohesive.
- Bread crumbs (in the method)
- Absorb liquid and give the filling body and a softer texture.
The step that matters
Adding the beaten eggs. Eggs set when heated, so they should be added to the hot mixture and cooked only briefly; overcooking can make them curdle or turn dry and grainy.
Swap the onion
