Why it works: Saffron and spirit work together. They rank in the top 17% of all ingredient pairs, and cooks put them together in 69 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Sugar Icing
Ingredients
Directions
Prepare the sugar
Combine sugar and starch and pound the mixture finely.
Sift the mixture through gauze.
Make the icing
Beat egg whites until frothy.
Gradually add powdered sugar while continuing to beat.
Whip for an additional 30 minutes, adding more sugar if icing is too thin.
Set aside some icing for decoration.
For colored icing, mix coloring with a little spirit.
Stir the colored mixture into the white icing until desired color is achieved.
Finish the cake
Spread icing smoothly over the cake with a knife after it comes out of the oven.
Dry the icing in a cool oven.
Use a cone made of stiff paper to squeeze colored icing for decoration.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to a foam that gives the icing its light, airy structure.
- Powdered sugar
- Sweetens the icing and, as it is beaten in, thickens it into a spreadable body.
- Fine white starch
- Stabilises the sugar so the icing stays smooth and white and does not weep.
The step that matters
Whipping in the sugar. Sugar must be added gradually while beating so the foam can absorb it. Adding it all at once collapses the egg white foam and leaves the icing thin and grainy.
Swap the saffron
The recipe marks saffron as optional. How well each one fits the dish's main ingredients (sugar, egg, spirit):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits better
- 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.
