Name: Suet Pudding
Ingredients: 1 cup sugar; 1 cup suet, finely chopped; 1 cup raisins or English currants, finely chopped; ½ cup sweet milk; 2 eggs; 1 teaspoon baking soda; Flour, as needed

Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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

What each ingredient does

Eggs: Bind the batter and add structure as the pudding sets.
Baking soda: Reacts with the batter to help it rise and lighten the texture.
Suet: Adds fat that keeps the pudding moist and rich.
Flour: Gives the batter body so it holds together as a cake-like pudding.
Sugar: Sweetens the pudding and helps browning and tenderness.
