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 ↓
Sugar Cookies. No. 1
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a bowl, mix sugar, milk, shortening, vanilla, eggs, baking powder, and salt.
Add flour gradually until the dough is very stiff.
Shape and bake
Roll the dough very thin.
Sift granulated sugar over the top.
Bake in a good oven at 400°F (200°C) until lightly golden.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Eggs
- Bind the dough and add richness and structure to the cookies.
- Shortening
- Provides fat that keeps the cookies tender and adds richness.
- Baking powder
- Releases gas to lift the dough so the cookies rise and lighten.
- Flour
- Forms the gluten network that gives the stiff dough its structure.
- Sugar
- Adds sweetness and promotes golden browning in the oven.
The step that matters
Add the flour gradually until the dough is very stiff. Flour absorbs liquid and builds gluten, so adding it too fast can leave pockets of dry flour or a dough that is hard to roll. Stopping at the stiff stage keeps the cookies tender and easy to shape thin.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, milk, egg, flour):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Blueberryfits less well
Fit is the average pairing score against sugar, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
“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.
