Tomato Sauce

Ingredients

Directions

Prepare the vegetables

  1. Wash and scrape the carrot thinly, then cut it into small pieces.

Make the sauce

  2. Pour in the tin of tomatoes and simmer slowly until soft enough to pass through a sieve.

  3. Rub the mixture through a sieve and return the juice to a clean pan.

  4. Thicken the juice with the rice flour, allow it to boil, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Melts to form the fat base that carries the vegetable flavours.
Tomatoes
Form the main body and acidity of the sauce once simmered and sieved.
Rice flour
Thickens the strained juice as it comes to a boil, giving the sauce body.
Onion
Adds savoury sweetness and aroma as it softens in the butter.

The step that matters

Simmer until soft, then sieve. The vegetables must be fully soft before rubbing through a sieve; undercooked pieces will not pass through and leave a grainy texture.

Fit is the average pairing score against butter, carrot, onion, leek, clove, garlic, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
