Why it works: Wheat and walnut match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 246 recipes. Both carry 1-hexanal, which smells fruit. The science ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
In a bowl, mix the whole wheat flour, wheat flour, and chopped walnuts.
In another bowl, combine sour milk, molasses, salt, and baking soda.
Mix and bake
Add the wet ingredients to the dry ingredients and mix until combined.
Pour the batter into a greased loaf pan.
Bake for 1 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
- Whole wheat flour
- Provides the main structure and the nutty, hearty body of the loaf.
- Sour milk
- Adds moisture and acidity that react with the baking soda to lift the batter.
- Baking soda
- Reacts with the acidic sour milk and molasses to release gas, helping the bread rise without yeast.
- Molasses
- Adds sweetness, dark colour, and moisture to the loaf.
- Chopped walnuts
- Add texture and a rich, nutty flavour throughout the bread.
The step that matters
Combine the wet and dry ingredients. Baking soda starts reacting as soon as it meets the acidic sour milk, so the batter should be mixed just until combined and moved to the pan promptly. Overmixing develops gluten and can make the loaf dense, while waiting too long lets some of the gas escape before baking.
Swap the walnut
How well each one fits the dish's main ingredients (wheat, flour, milk, molasses):
- Almondfits about as well
- Flaxseedfits about as well
- Walnutthe original
- Beansfits about as well
Fit is the average pairing score against wheat, flour, milk, molasses. Candidates are from the same food group and used in at least 100 recipes.
