Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Tea Cake Sandwich
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 the dough
Preheat your oven to 350°F (175°C).
In a bowl, rub the butter into the flour.
Add the sugar and beaten egg, mixing until stiff.
Roll the dough into two pieces on a floured surface.
Assemble and bake
Place one piece in a round tin and spread jam on top.
Cover with the second piece of dough, wetting the edges to seal.
Prick the top with a fork and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough once combined with fat and egg.
- Butter
- Rubbed into the flour to give the dough a tender, crumbly texture.
- Sugar
- Adds sweetness and helps the crust brown in the oven.
- Egg
- Binds the dough together and adds richness and structure.
- Jam
- Provides a sweet, fruity filling between the two layers.
The step that matters
Sealing the edges. If the edges are not wetted and pressed firmly, the top and bottom layers can separate or the jam can leak out during baking, leaving the sandwich poorly joined.
“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.
