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 ↓
Chocolate Cookies
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the dough
Melt the Baker's chocolate and let it cool slightly.
In a bowl, cream together the butter and sugar until light and fluffy.
Add the egg, sour milk, and vanilla to the mixture and mix well.
In a separate bowl, combine the flour, baking soda, raisins, and nuts.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Bake
Drop spoonfuls of dough onto a baking sheet.
Bake in a preheated oven at 350°F (175°C) for 10-12 minutes or until edges are golden.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and give the cookies a tender, rich texture.
- Flour
- Provides the structure that holds the cookies together as they bake.
- Baking soda
- Reacts with the sour milk to produce gas that helps the cookies rise.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tenderness.
- Egg
- Binds the dough and adds structure and moisture to the cookies.
- Sugar
- Sweetens the cookies and helps them brown at the edges as they bake.
The step that matters
Stirring in the dry ingredients. Once flour meets liquid, gluten begins to form. Stirring only until combined keeps the cookies tender rather than tough and dense.
Swap the raisin
How well each one fits the dish's main ingredients (chocolate, sugar, butter, egg, milk, nuts, vanilla):
- Coconutfits better
- Figfits better
- Bananafits better
- Raisinthe original
Fit is the average pairing score against chocolate, sugar, butter, egg, milk, nuts, vanilla. Candidates are from the same food group and used in at least 100 recipes.
