Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Black Walnut Loaf Cake
Ingredients
Directions
The book says “a moderate oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Soften the butter to a creamy consistency and place it in a mixing bowl.
Add the sugar, eggs, flour, baking powder, salt, milk, and vanilla, and beat hard for 5 minutes.
Stir in the chopped black walnuts until evenly mixed.
Bake and serve
Pour the batter into a greased and floured cake pan.
Bake at 300°F (150°C) covered for half the baking time, then uncover and continue baking until done.
Serve plain or iced.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb and moist texture.
- Eggs
- Provide structure and help bind the batter as it sets in the oven.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the loaf rises and becomes light.
- Black walnuts
- Add crunch and a strong nutty flavor throughout the loaf.
The step that matters
Covered baking for the first half. Baking covered at a low temperature for half the time keeps the top from drying and over-browning before the centre sets. Uncovering later lets the surface dry and colour.
Swap the walnut
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, milk, vanilla):
- Almondfits better
- Chestnutfits better
- Hazelnutfits better
- Walnutthe original
Fit is the average pairing score against butter, sugar, egg, flour, milk, vanilla. Candidates are from the same food group and used in at least 100 recipes.
