Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Pound Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

Preheat your oven to 350°F (175°C).

Make the batter

In a large bowl, cream together the sugar and butter until light and fluffy.
In a separate bowl, beat the eggs thoroughly, adding the egg whites last and folding them in carefully.
Add the grated lemon rind and juice to the mixture.
Dissolve the baking soda in cold water and mix it into the batter.
Gradually add the flour, mixing until just combined.

Bake

Pour the batter into a greased loaf pan and bake for about 1 hour or until a toothpick comes out clean.

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

What each ingredient does

Butter: Creamed with sugar to trap air, giving a tender, rich crumb and flavor.
Eggs: Provide structure and richness, and their proteins set as the cake bakes.
Flour: Forms the structure of the cake once its proteins set during baking.
Sugar: Creamed with butter to aerate the batter and add sweetness and gentle browning.
Baking soda: Reacts with the batter to produce gas that helps the cake rise.
