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.
Mix the batter
Sift together the flour, sugar, salt, and baking powder.
Add the chopped walnuts, then the egg and milk.
Rise and bake
Pour the mixture into a greased pan and let it rise for 20 minutes.
Bake in a preheated oven at 350°F (175°C) for one hour.

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 main structure that holds the loaf together as it bakes.
- Sugar
- Adds sweetness and helps the crumb brown and stay tender.
- Baking powder
- Releases gas in the wet batter and heat, lifting the loaf as it rises.
- Egg
- Binds the ingredients and helps set the crumb structure during baking.
- Walnuts
- Add crunch and a nutty flavor throughout the bread.
- Milk
- Hydrates the flour and gives the batter its moisture and spreadable texture.
The step that matters
Judge how much milk to add. Starting with 1 cup and adding more only as needed controls batter thickness. Too much milk thins the batter, so it spreads and rises less well, while too little leaves the flour dry and the loaf dense.
Swap the walnut
How well each one fits the dish's main ingredients (flour, sugar, egg, milk):
- Almondfits better
- Milletfits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against flour, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
