Why it works: Cocoa and milk work together. They rank in the top 10% of all ingredient pairs, and cooks put them together in 643 recipes. Both carry methyl 2-methylbutyrate, which smells fruity, apple. The science ↓

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

What each ingredient does

Flour: Provides the structure that sets the cake-like crumb as it bakes.
Baking powder: Releases gas during baking so the pudding rises and stays light.
Brown sugar: Dissolves into the hot water to form the rich, sweet fudge sauce beneath the cake.
Cocoa: Adds chocolate flavor and deep color to both the batter and the fudge sauce.
Shortening: Adds fat that tenderizes the crumb and carries flavor.

The step that matters

Pour hot water over all. The water must go on gently and evenly over the topping rather than being stirred in. As it bakes, the batter rises through the liquid and the sugar and cocoa dissolve into a sauce, so the pudding forms its own fudge layer.
