Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, baking powder, and salt.
Make the dough
Cut in the butter until the mixture resembles coarse crumbs.
Stir in the milk until just combined.
Roll the dough into two layers, each ½ inch thick.
Bake and assemble
Butter the layers well between and on top.
Bake 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 main structure as its proteins form gluten when mixed with liquid.
- Butter
- Cut into the flour to create layers and a tender, flaky texture, and adds richness.
- Baking powder
- Releases gas in the oven, helping the shortcake rise and become light.
- Milk
- Hydrates the flour to form the dough and adds moisture and browning.
The step that matters
Stir in the milk until just combined. Overmixing once the liquid is added develops too much gluten, which makes the shortcake tough instead of tender. Stop as soon as no dry flour remains.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
