Why it works: Flour and walnut are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 5,873 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Mix the flour, baking powder, sugar, walnuts, and salt in a bowl.
Add enough sweet milk to create a very stiff batter.
Pour the batter into a bread tin.
Let it stand in a warm place for 20 minutes.
Bake
Bake in a moderate oven at 350°F (175°C) for 30 to 45 minutes.

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.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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 structure of the loaf once it is mixed with milk and baked.
- Baking powder
- Releases gas in the batter, helping the loaf rise without yeast.
- Walnuts
- Add texture and body, and a nutty flavour to the crumb.
- Sugar
- Adds sweetness and helps the crust brown during baking.
- Sweet milk
- Hydrates the flour and sets the batter into a moist crumb as it bakes.
The step that matters
Keeping the batter very stiff. A stiff batter holds its shape and traps the gas from the baking powder, so the loaf rises upward rather than spreading or falling flat.
Swap the walnut
How well each one fits the dish's main ingredients (flour, sugar, milk):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Walnutthe original
Fit is the average pairing score against flour, sugar, milk. 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.
