Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Peanut Butter Dainties
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the peanut butter in a bowl.
Mix in the sugar and flour until smooth.
Add the well-beaten eggs and baking powder, and mix well.
Bake
Drop spoonfuls of the mixture onto buttered paper, ½ inch apart.
Bake in a moderate oven at 350°F (175°C) until golden brown.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Peanut butter
- Adds fat and rich peanut flavor, helping the cookies stay tender.
- Flour
- Provides the structure that holds the cookies together as they bake.
- Sugar
- Adds sweetness and helps the cookies brown at the edges.
- Eggs
- Bind the dough and add structure and moisture to the cookies.
- Baking powder
- Releases gas during baking so the cookies rise and lighten.
The step that matters
Bake until golden brown. Cookies keep firming as they cool, so pulling them once the edges turn golden keeps them soft rather than dry and brittle. Leaving ½ inch between spoonfuls allows them to spread without merging.
Swap the peanut
How well each one fits the dish's main ingredients (butter, flour, sugar, egg):
- Almondfits better
- Macadamia nutfits better
- Chestnutfits better
- Peanutthe original
Fit is the average pairing score against butter, flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
