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

What each ingredient does

Tomatoes
Provide the main body, flavour and acidity of the soup.
Sago
Thickens the soup as it cooks, giving it a smoother body.
Butter or fat
Carries the flavour of the ham and vegetables and adds richness.
Onion
Builds savoury sweetness and aroma when fried in the fat.
Lean ham
Adds savoury, meaty flavour to the base.

The step that matters

Sprinkling in the sago. Sago must be added to simmering liquid and stirred in so it does not clump; it thickens as its starch swells and turns clear when fully cooked.

Flavor stand-ins for the onion

  4. Onionthe original

Fit is the average pairing score against tomato, ham, butter, carrot, parsley, thyme, pepper. 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).
