Why it works: Saffron and spinach match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 149 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Sugar Icing
Ingredients
Directions
Make the icing
Combine the sugar and starch, pound finely, and sift through gauze.
Beat the egg whites until frothy, ensuring to beat in one direction.
Gradually add the powdered sugar to the egg whites while continuing to whip for 30 minutes.
Set aside a small amount of icing for decoration.
Color and apply
To color the icing, mix the coloring with a little clear spirit before adding it to the icing.
Spread the 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 writing 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 sweet, solid bulk of the icing once whipped with the egg whites.
- Fine white starch
- Adds body and helps keep the icing smooth and stable when dried.
- Egg whites
- Whipped into a foam that holds the sugar, giving the icing its light, airy structure.
The step that matters
Whipping the sugar into the egg whites. Adding the sugar too quickly or under-whipping can leave the icing lumpy or loose. Gradual addition while whipping builds a stable foam that sets smooth and firm when dried.
Swap the saffron
The recipe marks saffron as optional. How well each one fits the dish's main ingredients (sugar, egg, spinach, spirit):
- Cinnamonfits better
- Nutmegfits better
- Saffronthe original
- Gingerfits about as well
Fit is the average pairing score against sugar, egg, spinach, spirit. Candidates are from the same food group and used in at least 100 recipes.
