Why it works: Vanilla and almond match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,961 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together while beating continuously.
Slowly add the milk, then sift in the flour and baking powder, mixing gently.
Fold in the well-beaten egg whites.
Pour the batter into a long pan or two square layer‑cake tins.
Bake and ice
Bake until golden brown.
For the icing, beat together the powdered sugar, butter, and water, adding vanilla to taste.
If the icing is too thick, add more water.
Once the cake is cold, cut it into 1‑inch square pieces.
Ice five sides of each piece and dip in finely rolled peanuts or chopped almonds.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Egg whites
- Whipped and folded in to add lift and structure to the batter.
- Flour
- Forms the cake's main structure once the batter is baked.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Powdered sugar
- Dissolves into the butter and water to make a smooth, sweet icing.
The step that matters
Adding water to the icing. Powdered sugar icing sets firm as it cools, so adding water gradually keeps it spreadable. Too much water thins it into a runny glaze that will not hold on the cut pieces.
