Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the dough
Preheat your oven to 400°F (200°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the milk, baking soda, cream of tartar, and eggs; mix well.
Gradually add flour until a soft dough forms.
Flavor the dough with vanilla.
Shape and bake
Roll the dough thin and cut into desired shapes.
Place on a baking sheet and bake for 8-10 minutes or until lightly golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cookies a light, tender texture and rich flavor.
- Sugar
- Creams with butter for lift and adds sweetness and browning during baking.
- Eggs
- Bind the dough and add moisture and structure as the cookies set.
- Baking soda
- Reacts with the acid in cream of tartar to release gas, helping the cookies rise.
- Cream of tartar
- Acidic ingredient that works with baking soda to leaven the dough and soften texture.
- Flour
- Provides the structure that sets the cookies as they bake.
The step that matters
Gradually add flour until a soft dough forms. Adding flour too quickly or overmixing develops gluten and makes the cookies tough. Stopping once a soft dough forms keeps them tender.
