Why it works: Sugar and beetroot work together. They rank in the top 20% of all ingredient pairs, and cooks put them together in 780 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Icing for Cakes
Ingredients
Directions
Make the icing
Beat the egg white until stiff.
Gradually mix in the powdered sugar with a spoon.
Ice and decorate
Cover the cake with the icing.
Place the cake in a cool area until the icing is firm.
To color the icing pink, mix in beetroot juice or red currant jelly.
Use a piece of writing paper twisted like a sugar loaf, fill it with icing, and pipe designs as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Whipped into a stable foam that gives the icing its light, airy structure.
- Powdered sugar
- Sweetens the icing and stiffens the foam into a spreadable, pipeable consistency.
The step that matters
Beating the egg white until stiff. Egg white must form a firm foam to hold the sugar and set the icing. Under-beaten whites stay runny, while over-beaten whites turn dry and grainy and crack as they set.
Swap the beetroot
How well each one fits the dish's main ingredients (egg, sugar):
- Sweet potatofits better
- Capsicumfits better
- Asparagusfits better
- Beetrootthe original
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
