Why it works: Egg and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Tomato Fritters
Ingredients
Directions
Make the batter
In a bowl, combine the stewed tomatoes, egg, and baking soda.
Gradually add flour until the mixture is as stiff as pancake batter.
Fry
Heat lard in a frying pan over medium‑high heat.
Drop spoonfuls of the batter into the hot lard.
Fry until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stewed tomatoes
- Provide the main liquid and tomato flavour of the batter.
- Egg
- Binds the batter together and adds structure as it sets.
- Baking soda
- Reacts with the acidic tomatoes to produce gas that lightens the fritters.
- Flour
- Gives the batter body so it holds its shape in the hot fat.
- Lard
- Fries the batter, conducting heat and browning the outside.
The step that matters
Drop spoonfuls of the batter into the hot lard. If the lard is not hot enough, the batter absorbs fat and turns greasy and heavy instead of crisping. Adding batter only once the fat is hot sears the outside quickly, so the fritters hold their shape and brown evenly.
Swap the tomato
How well each one fits the dish's main ingredients (egg, flour):
- Arrowrootfits better
- Chivefits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against egg, flour. Candidates are from the same food group and used in at least 100 recipes.
