Why it works: Biscuit and flour match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 889 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Apple Dumplings
Ingredients
Directions
Prepare
Peel and slice the apples.
Make a biscuit crust.
Place the apples in a dish and sprinkle with a little coarse sea salt.
Steam the dumplings
Cover the apples with the crust and steam for 1.5 hours.
Make the sauce
Combine 1 cup of sugar, a piece of butter the size of a large egg, and 1 tablespoon of flour in a saucepan.
Add enough water to make the mixture as thin as syrup and heat until smooth.
Serve
Serve the dumplings inverted on a platter with the sauce.

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
- Apples
- Provide the fruit filling that softens and becomes tender during steaming.
- Sugar
- Sweetens the sauce and helps it thicken as it heats.
- Butter
- Adds fat and richness to the sauce, giving it a smooth, rounded flavour.
- Flour
- Thickens the sauce so it becomes smooth rather than watery.
The step that matters
Add enough water to make the mixture as thin as syrup and heat until smooth.. Flour thickens only when heated and stirred into liquid, so the mixture must be fully smooth before serving to avoid lumps and an uneven sauce.
Swap the apple
How well each one fits the dish's main ingredients (biscuit, sugar, egg, butter, flour):
