Why it works: Flour and butter 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 ↓
Spice Biscuits
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 the dough
Preheat the oven to 350°F (175°C).
In a bowl, mix the all-purpose flour, rice flour, sugar, mixed spices, and baking powder.
Add the eggs and softened butter, and mix until a dough forms.
Roll out the dough thinly and cut into narrow fingers.
Bake and assemble
Place the biscuits on a baking sheet and bake for about 20 minutes.
Once cooled, stick the biscuits together with jam and decorate with icing.

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
- All-purpose flour
- Provides the main structure of the dough as it sets in the oven.
- Rice flour
- Adds a crisp, fine texture to the biscuits.
- Granulated sugar
- Sweetens the biscuits and helps them brown during baking.
- Eggs
- Bind the dough together and add structure and richness.
- Unsalted butter
- Adds fat for tenderness and flavour in the dough.
- Baking powder
- Releases gas during baking so the biscuits rise slightly and lighten.
The step that matters
Rolling the dough thinly and cutting narrow fingers. Thin, narrow pieces bake evenly and dry out to a crisp texture. Thick pieces stay soft in the centre and may burn at the edges before they are cooked through.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
