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 handsome loaf cake.
Frost it thinly with plain white icing.
Let it dry before adding ornamentation.
Make the piping cone
Make a cone from stiff writing paper.
Secure it with paste or egg white.
Make the decorating icing
Mark a design on the dry icing with a pencil for vines, wreaths, or flowers.
In a bowl, combine half the icing sugar with the egg whites. Beat vigorously with a wooden paddle.
Add ½ teaspoon cream of tartar and half the remaining sugar. Beat longer.
Gradually add the rest of the sugar until the frosting reaches the right consistency to flow.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: acetic acid (sour, vinegar).
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
- Whipped to form the foam that gives the icing its structure and sheen.
- Icing sugar
- Sweetens the icing and, once beaten in, thickens it into a smooth, pipeable frosting.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a more stable foam.
The step that matters
Gradually add the rest of the sugar. Adding sugar in stages lets the foam stay stable while the icing thickens. Too much sugar at once can make it stiff or dense, and too little leaves it too runny to hold a design.
“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.
