The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: ethanol (alcoholic, ethereal).

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they 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

French chestnuts
Provide the main body and flavor of the purée once cooked and mashed.
Powdered sugar
Adds sweetness to the mashed chestnuts.
Hot milk
Moistens the mash so it can be pushed smoothly through a strainer.

The step that matters

Rubbing the mixture through a strainer. Pressing the mash through a fine strainer removes fibrous and lumpy bits, giving the smooth, fine texture that a Mont Blanc depends on. Cooling it before shaping lets it hold its pyramid form.

Swap the chestnut

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

  1. Chestnutthe original
  2. Almondfits about as well
  3. Hazelnutfits less well
  4. Pistachiofits less well

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