Ingredients: 1¾ cups butter; 2½ cups powdered sugar; 8 egg whites, beaten to a froth; 1 cup sweet milk; 1 teaspoon baking soda; 2 teaspoons cream of tartar; 1 teaspoon ground mace; ½ teaspoon vanilla extract; 1 nutmeg, grated; 5 cups all-purpose flour; 3 pounds mixed fruit (raisins, currants, and citron)

Why it works: Mace and nutmeg are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 6,557 recipes. Both carry myristicin, which smells spice, warm. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter: Creams with sugar to trap air and give the cake a tender, rich crumb.
Egg whites: Beaten to a froth, they add lift and structure to the batter.
Baking soda: Reacts with the acid in the batter to produce gas that helps the cake rise.
Cream of tartar: Acidic partner to baking soda, helping the leavening react and stabilising the egg foam.
All-purpose flour: Provides the main structure that sets as the cake bakes.
Mixed fruit: Adds moisture, sweetness and chewy texture throughout the cake.

The step that matters

Folding in the mixed fruit. Heavy fruit can sink to the bottom if the batter is overmixed or too loose. Folding gently and only until evenly distributed keeps the fruit suspended and avoids deflating the air in the batter.
