Custard Blanc-Mange

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the custard

  1. Combine milk, sugar, cornstarch, and salt in a saucepan.

  2. Stir over medium heat until thickened.

  3. Remove from heat and add vanilla extract.

Set and serve

  1. Soak gelatin in cold water for 5 minutes.

  2. Stir gelatin into the warm mixture until dissolved.

  3. Pour into a mold and refrigerate until set, about 4 hours.

  4. Unmold and serve chilled.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much aroma chemistry they share, and how many recipes mention both.

  1. Milk + vanillatop 5% of all pairs

Sugar and vanilla share little aroma chemistry, yet 35,032 recipes mention both: they likely work on texture and structure more than aroma.

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

What each ingredient does

Milk
Provides the liquid base and creamy body of the dessert.
Cornstarch
Thickens the milk as it heats, giving the blanc-mange its soft structure.
Sugar
Adds sweetness and helps balance the flavor of the milk.
Gelatin
Sets the mixture as it cools, giving a firm yet tender texture when chilled.

The step that matters

Stir gelatin into the warm mixture until dissolved. Gelatin must fully dissolve before setting; lumps or undissolved granules leave gritty spots and uneven firmness in the chilled dessert.
