What each ingredient does

Macaroni
Provides the starchy body and bulk that make the soup substantial.
Tomatoes
Form the flavorful liquid base of the soup, supplying acidity and color.
Flour
Thickens the tomato liquid by starch swelling when heated, giving a fuller texture.

The step that matters

Thickening with flour. Flour must be stirred into the tomato mixture and given time to heat, because raw flour left lumpy or undercooked tastes pasty and does not thicken evenly.
