Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Soda Biscuit
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 your oven to 400°F (200°C).
Make the dough
In a bowl, combine the flour, baking soda, and baking powder.
Add the lard and mix until crumbly.
Gradually add sour milk until a soft dough forms.
Knead the dough until smooth.
Shape and bake
Roll out and cut into desired shapes.
Bake in the preheated oven until golden.

Shared aroma: isobutyraldehyde (malty, green).
Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Flour
- Forms the structure of the biscuit as the dough sets in the oven.
- Baking soda
- Reacts with the sour milk to produce gas that helps the biscuits rise.
- Baking powder
- Adds additional leavening so the biscuits rise and become light.
- Lard
- Works into the flour to tenderize the crumb and add richness.
- Sour milk
- Provides moisture to bind the dough and its acidity activates the baking soda.
The step that matters
Gradually add sour milk. Adding the liquid slowly lets you stop once the dough is soft. Too much milk makes the dough sticky and tough, while too little leaves dry, crumbly biscuits that do not hold together.
