Ingredients

Directions

Make the icing

  1. Combine the sugar and starch, pound finely, and sift through gauze.

  2. Beat the egg whites until frothy, ensuring to beat in one direction.

  3. Gradually add the powdered sugar to the egg whites to maintain the froth.

  4. Continue whipping for an additional 30 minutes, adding more sugar if the icing is too thin.

  5. If coloring the icing, mix the coloring with a little colorless spirit before adding it to the icing until the desired tint is achieved.

Decorate and finish

  1. Set aside a small amount of icing for decoration.

  2. Spread the icing smoothly over the cake with a knife after it comes out of the oven.

  3. Dry the icing in a cool oven.

  4. Use a cone made of stiff paper to squeeze the colored icing for decoration.

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

What each ingredient does

Extra refined sugar
Forms the bulk of the icing and provides sweetness and a firm, set structure.
Egg whites
Whipped into a foam that gives the icing lightness and helps it hold its body.
Fine white starch
Helps keep the icing smooth and stable so it dries firm rather than soft.

The step that matters

Whipping in the sugar. Adding sugar gradually keeps the egg white foam from collapsing. Too much sugar at once deflates the froth, and the icing then becomes thin and runny.

Swap the saffron

The recipe marks saffron as optional. How well each one fits the dish's main ingredients (sugar, egg, spirit):

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Gingerfits better
  4. Saffronthe original

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