Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
In a large bowl, combine sugar, eggs, and milk.
Gradually add flour, baking soda, and cream of tartar, mixing until smooth.
Bake
Pour the batter into a greased baking dish.
Bake in a 400°F (200°C) oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the starch and gluten network that gives the bread its structure.
- Eggs
- Add protein that helps bind the batter and set it as it bakes.
- Milk
- Adds moisture and liquid that hydrates the flour and helps form the crumb.
- Sugar
- Adds sweetness and helps the crust brown during baking.
- Baking soda
- Reacts with the acid in the batter to release gas that makes the bread rise.
- Cream of tartar
- Supplies the acid that reacts with baking soda to produce rising gas.
The step that matters
Pour the batter into a greased baking dish.. Baking soda and cream of tartar start reacting as soon as they are moistened. Getting the batter into the oven promptly keeps that gas inside the batter, so the bread rises well instead of losing lift while it waits.
