Why it works: Butter and flour 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 ↓
Apple Pudding
Ingredients
Directions
Prepare the crust
Rub the butter into the flour until well combined.
Add enough water to form a paste.
Sprinkle flour inside a pudding bag and roll out the paste to fit inside.
Fill and boil
Fill the crust with peeled and cored apples.
Draw the crust together, trim any excess, and tie the bag tightly.
Place the bag in boiling water and boil for 2 hours.
Serve
Serve with sauce.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour 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
- Butter
- Adds fat that shortens the dough, giving it a tender, crumbly texture.
- Flour
- Forms the gluten structure of the paste that holds the pudding together while it boils.
- Apples
- Provide the fruit filling, with moisture that softens and sweetens as the pudding cooks.
The step that matters
Tying the bag tightly. If the bag is loose or not sealed, boiling water can seep in and soak the crust, and the filling may leak out. A firm seal keeps the pudding intact and moist during the long boil.
Swap the apple
How well each one fits the dish's main ingredients (butter, flour):
- Raisinfits better

- Applethe original
Fit is the average pairing score against butter, flour. Candidates are from the same food group and used in at least 100 recipes.
