Why it works: Raisin and flour 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 ↓
Duff Pudding
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.
Prepare
Preheat the oven to 350°F (175°C).
Butter a pudding dish.
Place the quartered apples in the dish.
Make and bake
In a bowl, mix the flour, sugar, cream of tartar, and baking soda.
Add the beaten eggs and melted butter to the dry ingredients and mix well.
Pour the mixture over the apples in the dish.
Bake until set and golden brown.
Serve
Serve with sauce.

Flour and butter 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
- Flour
- Provides the structure that sets the batter around the apples as it bakes.
- Eggs
- Bind the batter and help it set into a firm, sliceable pudding.
- Butter
- Adds richness and moisture, and helps the pudding brown at the edges.
- Sugar
- Sweetens the batter and contributes to golden browning in the oven.
- Cream of tartar
- Acidifies the batter and works with baking soda to lift and lighten the crumb.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that makes the pudding rise.
The step that matters
Bake until set and golden brown. Underbaking leaves the batter wet and gummy, while overbaking dries the crumb. The pudding is ready when the centre is set and the top is golden.
Swap the apple
How well each one fits the dish's main ingredients (raisin, flour, egg, sugar, cream, butter):
- Vanillafits better
- Figfits better
- Coconutfits better
- Applethe original
Fit is the average pairing score against raisin, flour, egg, sugar, cream, butter. Candidates are from the same food group and used in at least 100 recipes.
