Why it works: Egg and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Cream Biscuit
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Dissolve the baking soda in a little warm water and stir it into the sour cream.
Add the beaten egg white and salt, then mix well.
When the cream foams, quickly stir in enough sifted flour to form a soft dough.
Shape and bake
Roll out the dough and cut it into biscuit shapes.
Bake in a preheated oven at 400°F (200°C) until golden.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Sour cream
- Provides moisture and tang, and reacts with the baking soda to lift the dough.
- Baking soda
- Reacts with the sour cream's acidity to release gas, helping the biscuits rise.
- Egg white
- Adds structure and helps bind the dough as it sets in the oven.
- Flour
- Forms the dough's structure, which sets and holds the biscuit shape when baked.
The step that matters
Stir in the flour quickly once the cream foams. The soda and sour cream's acid react right away and release gas. Delaying the flour lets that gas escape, so the biscuits rise less and turn out denser.
