Make the dough
Cream together the sugar and butter until smooth.
Add the eggs and mix well.
Dissolve the baking soda in the sour milk and add to the mixture.
Knead the dough until soft.
Bake
Shape into cookies and bake in a hot oven at 400°F (200°C) until lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add richness and structure to the cookies.
- Baking soda
- Reacts with the sour milk to produce gas, helping the cookies rise and turn tender.
- Sour milk
- Its acidity activates the baking soda and adds moisture to the dough.
- Butter
- Adds fat for tenderness and flavor, and creams with the sugar to lighten the dough.
- Sugar
- Sweetens the cookies and helps them brown during baking.
The step that matters
Dissolve the baking soda in the sour milk and add to the mixture.. Baking soda needs an acid to react with; the sour milk supplies it. Dissolving the soda evenly prevents bitter pockets and uneven rising.
“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.
