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

What each ingredient does

Eggs
Cooked yolks form a smooth, rich base that gives the paste its body.
Powdered sugar
Adds sweetness and dissolves into the yolks for a fine, smooth texture.
Butter
Supplies fat for richness, and it firms as it cools so the pieces hold their shape.
Orange-flower water
Adds a light floral aroma that flavours the paste.

The step that matters

Pound the yolks with the sugar until smooth. Any lumps left in the yolk and sugar mixture will not blend evenly with the butter and can clog the cloth, so the pieces will come out uneven. Thorough pounding gives a uniform paste that passes through the holes cleanly.

Swap the orange

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

  1. Vanillafits better
  2. Lemonfits better
  3. Raisinfits better
  4. Orangethe original

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