Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Cake with Ornamental Frosting.
Ingredients
Directions
Prepare the cake
Bake a loaf cake and frost it thinly with plain white icing.
Let the icing dry before adding ornamentation.
Make the royal icing
Combine half the icing sugar with the egg whites in a bowl and beat vigorously with a wooden paddle.
Add cream of tartar and half the remaining sugar, then beat longer.
Gradually add the rest of the sugar until the icing is the right consistency to flow through the cone.
Decorate
Make a cone from stiff writing paper and secure it with paste or egg white.
Mark a design on the dry icing with a pencil for vines, wreaths, or flowers.
Fill the cone three-fourths full, fold the end down, and cut off the point to create the desired hole size.
Guide the cone with your left hand and press the icing out with your right thumb, following the marked lines.

Egg and cream barely smell alike, yet cooks put them together in 42,166 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whip into a foam that gives the icing its structure and sets it firm as it dries.
- Fine icing sugar
- Provides sweetness and bulk, and stiffens the icing as it is added.
- Cream of tartar
- Stabilises the egg white foam so it holds its shape and does not collapse.
The step that matters
Gradually add the sugar to reach the right consistency. Too little sugar leaves the icing runny and it will spread or fail to hold lines; too much makes it stiff and hard to press through the cone. Adding sugar slowly lets you stop at the point where it flows smoothly yet keeps its shape.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
