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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Sift together the flour, baking powder, salt, and sugar.
Add the sweet milk and beaten egg to the dry ingredients.
Fold in the broken walnuts.
Let the mixture rise for 20 minutes.
Bake
Bake in a preheated oven at 350°F (175°C) for 30 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Baking powder
- Releases gas in the batter, making the bread rise and become light.
- Egg
- Adds structure and binds the batter as it sets in the oven.
- Walnuts
- Add crunch and a rich, nutty flavour to the crumb.
- Flour
- Provides the main structure as its starch sets during baking.
- Sweet milk
- Hydrates the flour and adds moisture and tenderness to the crumb.
The step that matters
Let the mixture rise for 20 minutes. Baking powder starts releasing gas as soon as it is wet, so the batter should rise before baking. Delaying the bake or overmixing after folding in the walnuts can knock out gas and leave a denser loaf.
Swap the walnut
How well each one fits the dish's main ingredients (flour, sugar, milk, egg):
- Almondfits better
- Milletfits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against flour, sugar, milk, egg. 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.
