Why it works: Butter and milk 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 ↓
Saggerton Jumbles
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream together the butter and castor sugar.
Add the beaten egg and stir in the milk, beating slightly.
Mix the lemon juice and grated lemon rind into the mixture.
Combine the cream of tartar and baking soda, then stir into the flour.
Gradually sift in the flour until the paste is thick.
Shape and bake
Knead and roll out the dough very thin.
Cut into shapes with a pastry cutter or into ovals and circles.
Bake in a 400°F (200°C) oven for 5 minutes.

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
- Butter
- Creaming with sugar traps air and gives the jumbles a tender, rich texture.
- Castor sugar
- Sweetens the dough and, creamed with butter, helps create a light structure.
- Egg
- Binds the dough and adds richness and structure as it sets in the oven.
- Cream of tartar
- Acidifies the dough and reacts with baking soda to help the jumbles rise and lighten.
- Baking soda
- Reacts with the acid in the dough to produce gas, helping it rise and spread lightly.
- Flour
- Provides the structure that holds the dough together and sets as it bakes.
The step that matters
Rolling the dough very thin. Thin dough bakes quickly and evenly, so the jumbles turn crisp and golden rather than thick and doughy. Dough rolled too thick may stay soft in the centre.
