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 ↓
Old-Fashioned Jumbles
Ingredients
Directions
The book says “a moderate oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 400°F (200°C).
Cream together the sugar and butter.
Add the eggs, lemon juice, and lemon rind, mixing well.
Gradually add enough flour to form a thin dough.
Shape and bake
Break off pieces the size of an egg and roll them into long strips.
Tie the strips into knots or wind them into circles.
Place on a baking sheet and bake until golden.

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
- Sugar
- Sweetens the dough and helps it cream with the butter to a light base.
- Butter
- Adds fat for tenderness and richness, and carries flavour through the dough.
- Eggs
- Bind the dough and add richness and structure as the jumbles set in the oven.
- Lemon
- Juice and rind add acidity and bright aroma that cut through the sweetness.
- Flour
- Provides the structure that lets the thin dough hold its knotted or circular shape.
The step that matters
Gradually add enough flour to form a thin dough. Adding flour gradually lets you judge the dough's texture. Too much flour makes it stiff and dry, so the shaped pieces will not roll into smooth strips or bake tender.
