Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Plain Jumbles
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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Beat the butter and sugar together until creamy.
Whisk the eggs until very thick, then add to the butter and sugar mixture.
Stir in the essence of lemon.
Dissolve the saleratus in a little water and mix it with the milk.
Pour the milk mixture into the batter and mix well.
Shape and bake
Shape the dough into jumbles and place them on a baking sheet.
Bake until golden brown.

Flour and butter 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
- Flour
- Forms the main structure of the dough once it is mixed with the liquids.
- Butter
- Adds fat and tenderness, and helps the cookies brown in the oven.
- Eggs
- Add structure and richness, and whisking them thick traps air for lift.
- Saleratus
- Releases gas when dissolved and reacts with the batter to help it rise.
- Sugar
- Sweetens the dough and helps it brown and become crisp at the edges.
The step that matters
Bake until golden brown. Baking soda-type leaveners react quickly once dissolved, so the dough should be shaped and baked promptly. Watching for golden brown colour avoids both pale, underbaked jumbles and dark, dry ones.

Fit is the average pairing score against flour, sugar, milk, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
