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 ↓

Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Sift the flour, baking powder, and salt together.
Rub in the shortening.
Add the water, knead quickly, and roll out into a very thin sheet.
Fill and roll
Brush the dough with melted butter.
Sprinkle the chopped dried apples and sugar over the dough.
Roll up the dough and place it in a buttered baking pan.
Brush the roll with water and bake at 350°F (175°C) for 45 minutes.
Bake and serve
After 30 minutes, baste with the dissolved sugar and water mixture, then return to the oven to glaze.
Serve hot with cream and sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough that holds the filling inside the roll.
- Baking powder
- Releases gas in the dough, helping it rise and turn light.
- Shortening
- Rubbed into the flour, it tenderizes the dough and keeps it flaky.
- Dried apples
- Provide the fruit filling, with concentrated sweetness and flavor once softened.
- Sugar
- Sweetens the filling and, dissolved for basting, helps the roll brown and glaze.
- Melted butter
- Brushed on the dough, it adds richness and helps browning in the oven.
The step that matters
Basting with the sugar and water mixture. Sugar dissolved in water brushed onto the roll caramelizes as it bakes, forming a glaze. Basting at the right point keeps the surface from burning before the glaze sets.
Swap the apple
How well each one fits the dish's main ingredients (flour, butter, sugar):
- Raisinfits better
- Vanillafits better
- Figfits better
- Applethe original
Fit is the average pairing score against flour, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
