Mock Bisque Soup

Ingredients

Directions

Prepare the milk base

  1. Scald the onion with the milk.

  2. Remove the onion and thicken the milk with flour diluted in cold water, ensuring no lumps remain.

  3. Cook in a double boiler for twenty minutes, stirring constantly at first, then occasionally.

Prepare the tomatoes

  1. In a saucepan, cook the tomatoes until most moisture is gone, yielding about two cups of pulp.

  2. Rub the tomato pulp through a strainer, then add sugar and baking soda.

Combine and serve

  1. Combine the tomato mixture with the thickened milk, then strain into a hot soup tureen over butter, salt, pepper, and Tabasco sauce.

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

What each ingredient does

Milk
Forms the creamy body of the soup once thickened with flour.
Flour
Thickens the scalded milk into a smooth, lump-free base.
Tomatoes
Provide the main flavour and acidity, reduced and strained into pulp.
Baking soda
Neutralises some of the tomato acidity, softening the sharp taste.
Butter
Adds richness and fat, melting into the hot soup for mouthfeel.
Sugar
Balances the acidity of the tomatoes with a touch of sweetness.

The step that matters

Thicken the milk without lumps. Flour must be diluted in cold water before it meets hot milk; added dry or undiluted it clumps, and the starch cannot disperse evenly to give a smooth thickened base.

Swap the onion

How well each one fits the dish's main ingredients (milk, butter, flour, tomato, pepper, sugar, sauce):

  1. Capsicumfits better
  2. Potatofits better
  3. Sweet potatofits better
  4. Onionthe original

Fit is the average pairing score against milk, butter, flour, tomato, pepper, sugar, sauce. Candidates are from the same food group and used in at least 100 recipes.
