Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sultana Scones
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
Rub butter into the flour.
Mix in sugar, baking soda, cream of tartar, and salt.
Beat the egg. Set aside a little to brush over the scones.
Add buttermilk to the beaten egg.
Combine to form a light dough.
Shape and bake
Roll out the dough to about ½ inch thick.
Brush with the reserved egg.
Bake for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the structure of the scones as its proteins hydrate and set in the oven.
- Baking soda
- Reacts with the acidic buttermilk and cream of tartar to produce gas that makes the scones rise.
- Cream of tartar
- Provides acidity that works with the baking soda to leaven the dough and adds tang.
- Buttermilk
- Adds moisture and acidity, tenderizing the dough and activating the leavening.
- Butter
- Coats flour particles and creates tenderness and flakiness as it stays solid in the dough.
- Egg
- Adds richness and structure, and the beaten egg brushed on top promotes browning.
The step that matters
Combine to form a light dough. Overworking the dough develops gluten and makes scones tough, while mixing only until combined keeps them tender and lets the leavening lift them evenly.
Swap the raisin
How well each one fits the dish's main ingredients (flour, sugar, buttermilk, cream, butter, egg):
- Raisinthe original
- Vanillafits about as well
- Lemonfits less well
- Coconutfits less well
Fit is the average pairing score against flour, sugar, buttermilk, cream, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
