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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 400°F (200°C).
In a large bowl, beat the eggs until light and fluffy.
Make the batter
Add the flour, sweet milk, lard, and salt; mix until smooth.
Bake
Pour the batter into a greased baking dish.
Bake in the preheated oven until golden and puffed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs give the batter structure and help it puff and rise in the oven.
- All-purpose flour
- Flour provides the starch and protein that set the batter into a sturdy, cake-like crumb.
- Sweet milk
- Milk supplies the liquid that turns the flour into batter and adds moisture and browning.
- Lard
- Lard adds fat that tenderises the crumb and helps the surface brown.
The step that matters
Baking in a hot, preheated oven. The batter relies on steam and rapid heat to puff up quickly. If the oven is not fully preheated, or the batter sits too long before baking, the cake may rise poorly and turn out dense.
Swap the walnut
How well each one fits the dish's main ingredients (egg, flour, milk):
- Almondfits better
- Milletfits better
- Chestnutfits about as well
- Walnutthe original
Fit is the average pairing score against egg, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
