Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Tea Biscuit
Ingredients
Directions
The book says “a very quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix flour, shortening, baking powder, and salt.
Add enough cold sweet milk to form a soft dough.
Shape the biscuits
Roll the dough on a floured surface to about ½ inch thick.
Spread the soft butter over the dough and sprinkle with sugar.
Roll the dough like a jelly roll.
Slice the rolled dough into biscuits, each ½ inch thick.
Place the biscuits in a floured pan, leaving space between them.
Bake
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the structure of the dough once mixed with liquid.
- Baking powder
- Releases gas that makes the biscuits rise and become light.
- Shortening
- Coats flour particles to keep the biscuits tender and flaky.
- Soft butter
- Adds fat between dough layers for flavour and a tender, flaky texture.
- Sugar
- Adds sweetness and helps the surface brown.
The step that matters
Rolling the dough like a jelly roll. Butter and sugar must spread evenly across the dough, and the roll must be snug but not torn. Uneven spreading gives patchy layers and a dense, uneven texture.
“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.
