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 ↓
Apple Strudel
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.
Make the dough
Mix flour with water and knead into a loose, flabby dough.
Place the dough in the center of a floured surface and pull and spread it thin like tissue paper until it covers the table.
Fill and roll
Spread the sliced apples evenly over the dough, then sprinkle with cinnamon, sugar, raisins, and melted butter.
Take one end of the dough and roll it up like a jelly roll until it meets the other end.
Cut the rolled dough into small pieces and place them in a baking dish.
Bake and serve
Bake in a preheated oven at 350°F (175°C) until golden brown.
Serve plain or with cream.

Cinnamon and sugar barely smell alike, yet cooks put them together in 30,779 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
- Flour
- Forms the dough's structure, which stretches thin and holds the filling together.
- Butter or fat
- Adds richness and moisture, and helps the pastry turn golden brown in the oven.
- Apples
- Provide the main filling, bringing moisture and tartness that contrast with the sugar.
- Sugar
- Sweetens the filling and helps the exposed pastry brown.
The step that matters
Pulling the dough thin. Stretching the dough until it is thin enough to see through gives a flaky, tender layered pastry. If it is left thick, the strudel becomes dense and doughy rather than light.
Swap the apple
How well each one fits the dish's main ingredients (flour, butter, cinnamon, sugar, raisin):
- Vanillafits better
- Figfits better
- Applethe original
- Coconutfits about as well
Fit is the average pairing score against flour, butter, cinnamon, sugar, raisin. Candidates are from the same food group and used in at least 100 recipes.
“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.
