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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the tomatoes
Wash and wipe the tomatoes, but do not peel them.
Slice the tomatoes and dust each piece with paprika, coarse sea salt, and sugar, then sprinkle with a few drops of onion juice.
Coat and fry
Dip the slices in fine cornmeal.
In a deep pan, heat cooking oil to 400°F (200°C).
Fry the coated tomato slices until golden brown.
Serve
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 a juicy centre that softens inside while the coating crisps outside.
- Fine cornmeal
- Forms a crisp, golden coating that browns during frying.
- Cooking oil
- Conducts heat to cook the slices quickly and brown the cornmeal coating.
The step that matters
Frying at 400°F (200°C). Oil that is too cool lets the cornmeal soak up grease and turn soggy, while oil that is too hot browns the coating before the tomato warms through. Hold the heat steady and fry until the coating is golden.
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.
“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.
