Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
French Loaf 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 the oven to 350°F (175°C).
Make the batter
Cream together the butter and sugar until light and fluffy.
Add the sweet milk and mix well.
In a separate bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the beaten egg whites gently.
Bake
Pour the batter into a greased loaf pan.
Bake for 30-40 minutes or until a toothpick inserted in the center comes out clean.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Egg whites add structure and lift to the batter as they set in the oven.
- Cream of tartar
- Acidifies the batter so it reacts with the baking soda to help the cake rise.
- Baking soda
- Reacts with the acid in the batter to produce carbon dioxide for rising.
- Butter
- Creaming with sugar traps air and adds fat for a tender crumb.
- Flour
- Provides the structure that sets the cake's crumb as it bakes.
The step that matters
Folding in the beaten egg whites. Egg whites hold air that gives the cake its lift. Folding gently keeps that air in; vigorous stirring deflates the batter and leaves a dense loaf.
