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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 400°F (200°C).
Make the dough
In a large bowl, combine the flour, salt, baking powder, baking soda, and cream of tartar.
Cut in the lard until the mixture resembles coarse crumbs.
Stir in the milk until just combined.
Knead the dough quickly on a floured surface.
Roll out to about ½ inch thick and cut into desired shapes.
Bake
Place on a baking sheet and bake for 10-12 minutes or until golden.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
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 main structure once wet and kneaded into dough.
- Lard
- Cut into the flour to create tenderness and flaky texture in the biscuit.
- Milk
- Hydrates the flour and dissolves the leavening, forming the dough.
- Baking powder
- Releases gas in the dough to lift and rise the biscuits in the oven.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas for additional rising.
- Cream of tartar
- Acidic ingredient that reacts with baking soda to help leavening.
The step that matters
Knead the dough quickly. Overworking wheat dough develops gluten, making biscuits tough rather than tender. Brief handling keeps them light, so the dough should be handled as little as possible.
“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.
