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 ↓
Baked Tomatos, Stuffed with Macaroni and Cheese
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cook the macaroni in boiling water until soft.
Cut a small opening in the top of each tomato and remove the seeds with a teaspoon, keeping as much pulp as possible.
Fill and bake
Fill the tomatoes with macaroni, then add butter, salt, and pepper.
Top with cheese.
Bake in a moderate oven at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Hold the filling and become tender and juicy as they bake, forming the dish's container.
- Macaroni
- Provides the bulk of the filling, soaking up juices and setting into a soft, starchy mass.
- Cheese
- Melts over the top and browns in the oven, adding savoury flavour and a golden crust.
- Butter
- Adds richness and moisture to the macaroni and helps it brown lightly.
The step that matters
Removing the seeds while keeping the pulp. Scooping too deeply or tearing the walls can make the tomato shells thin or leaky. Keeping the pulp preserves flavour and moisture, and the shell must stay intact to hold the filling during baking.
Swap the walnut
How well each one fits the dish's main ingredients (tomato, cheese, butter, pepper):
- Beansfits better
- Chickpeafits about as well
- Walnutthe original
- Lima beansfits about as well
Fit is the average pairing score against tomato, cheese, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
