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 the dough
Preheat the oven to 400°F (200°C).
In a large bowl, mix the flour, cream of tartar, and baking soda.
Add the sweet milk and lard, and stir until combined.
Knead the dough lightly on a floured surface.
Roll out the dough to about ½ inch thick and cut into biscuit shapes.
Bake
Place the biscuits on a baking sheet and bake for 12-15 minutes or until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Forms the structure that holds the biscuits together as they bake.
- Cream of tartar
- Acidic component that reacts with baking soda to produce gas for rising.
- Baking soda
- Alkaline leavener that releases carbon dioxide when combined with acid, lifting the dough.
- Sweet milk
- Hydrates the flour to form dough and adds moisture and softness.
- Lard
- Fat that tenderises the crumb and helps the biscuits brown.
The step that matters
Knead the dough lightly. Overworking soda biscuit dough develops gluten and makes the biscuits tough. Light handling keeps them tender, and the leavening reaction starts as soon as the wet and dry ingredients meet, so the dough should be shaped and baked promptly.
“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.
