Arrowroot Blanc-mange

Ingredients

Directions

Make the blancmange

  1. In a saucepan, combine 1½ cups of milk, sugar, and your choice of nutmeg or lemon for seasoning.

  2. Mix the arrowroot smoothly with the remaining ½ cup of milk.

  3. Bring the milk mixture to a boil over medium heat.

  4. Quickly pour in the arrowroot mixture while stirring continuously.

  5. Allow it to boil for 2-3 minutes until thickened.

Set and serve

  1. Wet a mold with cold milk and pour the arrowroot mixture into it.

  2. Let it cool, then turn it out as you would for calf's-foot jelly.

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

What each ingredient does

Arrowroot
Thickens the milk into a smooth, set custard-like body as it boils.
Milk
Forms the liquid base that the arrowroot thickens into the blancmange.
Sugar
Adds sweetness to the milk base.

The step that matters

Stirring in the arrowroot mixture. Pouring the arrowroot in quickly while stirring keeps it dispersed, so it thickens evenly instead of forming lumps. Arrowroot thickens when it boils, so the mixture must be kept moving until it does.

Swap the arrowroot

How well each one fits the dish's main ingredients (milk, sugar, nutmeg):

  1. Sweet potatofits better
  2. Arrowrootthe original
  3. Capsicumfits about as well
  4. Parsnipfits about as well

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