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

What each ingredient does

Marshmallows
Melt into a smooth, sticky base that gives the paste its body and binding.
Milk
Adds moisture and richness, softening the marshmallow base into a spreadable texture.
Sugar
Sweetens the paste and helps it set firm as it cools.
Pistachio nuts
Provide the main nutty flavor and a slightly grainy texture throughout the paste.

The step that matters

Boil milk and sugar without stirring. Stirring a boiling sugar syrup can encourage crystals to form, leading to a grainy texture. Boiling it undisturbed for the full six minutes helps it reach the right concentration to set smoothly once combined and beaten.

Swap the nuts

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

  1. Cashew nutfits better
  2. Hazelnutfits better
  3. Brazil nutfits better
  4. Nutsthe original

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