Scotch 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.
Prepare
Preheat the oven to 350°F (175°C).
In a large bowl, combine the flour and powdered sugar.
In another bowl, whip the butter and lard until creamy.
Add the butter and lard mixture to the flour and sugar, mixing until crumbly.
Shape and bake
Press the mixture together with your hands to form small cakes.
Place the cakes on a baking sheet and bake until light brown.

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 structure that holds the cakes together after shaping.
- Powdered sugar
- Adds sweetness and dissolves finely, giving the cakes a tender crumb.
- Unsalted butter
- Adds fat and richness, contributing moisture and a tender texture.
- Lard
- Adds fat that keeps the crumb tender and helps the cakes brown.
The step that matters
Mixing until crumbly. Work the fat into the flour only until the mixture crumbles. Overworking develops gluten in the flour, which makes the cakes tough rather than short and tender.
“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.
