Oven, in the book's wordsA quick oven

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. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, baking powder, and salt.
In another bowl, whisk together the milk, eggs, and melted butter.

Make and bake

Combine the wet and dry ingredients until just mixed.
Pour the batter into a greased baking dish.
Bake for 20-25 minutes until golden brown.

Flour and butter 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

All-purpose flour: Provides the main structure as the starch and protein set during baking.
Eggs: Add structure and richness, helping the batter set and hold its shape.
Milk: Adds moisture and helps the batter bake up tender.
Baking powder: Releases gas during baking, helping the batter rise.
Butter: Adds fat for richness and tenderness, and aids browning.
Sugar: Adds sweetness and helps the crust brown.

The step that matters

Combine the wet and dry ingredients until just mixed. Overmixing develops gluten in the flour, which makes the batter tough and can stop it rising evenly. Stirring only until the flour is moistened keeps the texture light.
