Why it works: Butter and milk 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 ↓
Soda Biscuit
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.
Make the dough
In a large bowl, cream together the butter and sugar.
Gradually add the sifted flour and mix well.
Dissolve the baking soda in the warm milk and add it to the mixture.
Combine everything into a dough and turn it out onto a floured surface.
Knead the dough gently, then roll it out to about ¼ inch thick.
Shape and bake
Cut the dough into cakes and prick each one with a fork.
Place the cakes on a baking sheet and bake in a moderate oven at 350°F (175°C) 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 the liquid.
- Butter
- Adds richness and tenderness by coating the flour and creaming with sugar.
- Sugar
- Sweetens the biscuit and helps it brown as it bakes.
- Baking soda
- Reacts with the milk to produce gas that lightens the biscuit.
- Milk
- Hydrates the flour and helps bind the dough together.
The step that matters
Dissolving the baking soda in the warm milk. Baking soda must be fully dissolved so it reacts evenly throughout the dough. Unevenly distributed soda can leave bitter patches or pockets of uneven rise.
