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 ↓
Short Cake Crust
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Sift flour and salt together.
Dissolve baking soda in sour milk and stir gradually into the flour.
Add sour cream or melted butter.
Mix until a soft dough forms; if too sticky, add a little more flour.
Shape and bake
Roll out to ½ inch thickness and cut with a biscuit cutter.
Place on a buttered baking sheet and bake at 350°F (175°C) for 15 minutes.

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
- Flour
- Provides the structure that holds the dough together as it bakes.
- Baking soda
- Reacts with the sour milk to produce gas that lifts the dough.
- Sour milk
- Its acidity activates the baking soda and adds tenderness.
- Sour cream or melted butter
- Adds fat, which tenderizes the crust and adds richness.
The step that matters
Adding flour to a sticky dough. Too much extra flour makes the crust dry and tough, while too little leaves it sticky and hard to cut cleanly. Add flour only in small amounts until the dough is soft but workable.
“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.
