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
Make the dough
Sift the flour into a bowl and make a hole in the center.
Pour in the warm water, melted butter, whole eggs, egg yolks, and salt.
Stir slowly to form a smooth dough.
Cover and let it rest in a warm place.
Peel and finely slice the apples.
Fill and roll
Flour a clean tablecloth.
Roll out the dough as thin as possible.
Gently stretch the dough with your hands to make it even and thin.
Pour melted butter over the dough.
Mix the apples with brown sugar, cinnamon, raisins, and citron.
Lift the tablecloth at the corners.
Roll the strudel.
Bake
Place the rolled strudel in a buttered pan and dot with butter.
Bake for about 15 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 gluten structure that makes the dough stretch thin without tearing.
- Eggs
- Add structure and richness to the dough, helping it hold together when stretched.
- Butter
- Adds fat for tenderness and flavor, and helps the pastry brown in the oven.
- Apples
- Provide the main filling, releasing moisture that cooks down into the strudel's juicy centre.
- Cream
- Poured over during baking, it enriches the filling and adds moisture and browning.
The step that matters
Stretching the dough thin. Gluten needs to rest and relax so the dough stretches thin without tearing. Thin layers bake up flaky and let the filling cook evenly, while thick dough stays dense and doughy.
Swap the apple
How well each one fits the dish's main ingredients (flour, butter, egg, sugar, cinnamon, raisin, cream):
- Vanillafits better

Fit is the average pairing score against flour, butter, egg, sugar, cinnamon, raisin, cream. Candidates are from the same food group and used in at least 100 recipes.
