Why it works: Macadamia nut and flour match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 124 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare
Heat oven to 350 degrees.
Grease an 8‑inch square baking pan.

Beat in the flour mixture until blended.
Add milk, reserved melted butter, and vanilla, beating until blended.
Pour the batter into the pan.
Bake 35 minutes or until done.
Unmold and serve

Shared aroma: 2,3-pentanedione (butter, sweet).
Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Bind the batter and give the cake its structure as they set in the oven.
- Butter
- Adds richness and fat that makes the cake tender and carries the flavor of the topping.
- Flour
- Forms the cake's structure once heated, holding the crumb together.
- Baking powder
- Releases gas that lifts the batter so the cake rises and stays light.
- Dark brown sugar
- Melts into the glaze that caramelizes on top, adding moisture and deep sweetness.
- Dark corn syrup
- Keeps the glaze smooth and prevents the sugar from crystallizing.
The step that matters
Invert the cake and remove the pan. The cake must cool briefly so it sets enough to hold its shape, but not so long that the caramel glaze hardens and sticks to the pan, which would tear the topping away.
