Why it works: Tomato and onion are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 20,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fried Tomatoes in Batter
Ingredients
Directions
Prepare the tomatoes
Wash and wipe the tomatoes without peeling them.
Slice the tomatoes and dust each piece with paprika, salt, and sugar. Sprinkle with a few drops of onion juice.
Dip the slices in fine cornmeal.
Batter and fry

Dip the cornmeal-coated tomatoes in the batter.
Fry in deep, hot oil until golden brown.
Serve dry with fish or chops.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Provide the main filling and juicy interior that the coating surrounds.
- Flour
- Forms the batter that crisps and browns around the tomato slices when fried.
- Egg
- Binds the batter so it coats the tomato slices evenly.
- Milk
- Thins the batter to a coating consistency and adds browning through milk sugars.
- Fine cornmeal
- Adds a crunchy, golden crust on the outside of the tomato slices.
The step that matters
Fry in deep, hot oil until golden brown. If the oil is not hot enough, the coating absorbs oil and turns greasy before it crisps. Hot oil seals the crust quickly, keeping the tomato slices from soaking up fat and falling apart.
Swap the onion
How well each one fits the dish's main ingredients (tomato, flour, milk, egg, sugar):
- Capsicumfits better
- Sweet potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against tomato, flour, milk, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
