Name: Raisin Bread
Ingredients: 1 egg; 1 cup Hiawatha raisins; 1 cup sugar; 1 cup chopped nuts; 4 cups flour; 1 teaspoon Hiawatha salt; 4 teaspoons baking powder; 1 cup milk

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 ↓

Raisin Bread

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

Preheat the oven to 350°F (175°C).

Make and bake the batter

In a large bowl, mix the egg, raisins, sugar, chopped nuts, flour, salt, baking powder, and milk.
Let the mixture stand for 20 minutes.
Pour the batter into a greased loaf pan.
Bake for 1 hour or until golden brown.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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: Binds the batter and adds structure as it sets in the oven.
Flour: Forms the main structure of the loaf as the batter sets.
Baking powder: Releases gas during baking so the loaf rises and becomes light.
Sugar: Sweetens the loaf and helps the crust brown.
Milk: Hydrates the flour and adds moisture and tenderness to the crumb.
