Why it works: Malt and vanilla share more aroma than cooks usually use. They rank in the top 6% of all ingredient pairs, and 22 recipes mention both. Both carry beta-damascenone, which smells apple, rose. The science ↓
The recipe
Ingredients
Contains: egg, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: breadcrumbs
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Separate the eggs.
Beat the yolks until stiff.
Add the grated lemon rind and malt gradually, beating vigorously.
Beat the egg whites until very stiff.
Add a pinch of salt to the egg whites and beat until frothy.
Add lemon juice and beat until stiff and crumbly.
Fold the yolk mixture into the egg whites.
Fold in the nut meal and gluten or bread crumbs gently.
Bake and cool
Bake in a 350°F (175°C) oven in a cake tin without oiling.
Turn the cake bottom side up on another tin to cool, allowing air circulation.

Sugar and vanilla share little aroma chemistry, yet 35,031 recipes mention both: they likely 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
- Egg whites trapped in the batter provide the air and structure that lift the cake.
- Malt
- Adds sweetness and a distinctive malty flavour and colour to the cake.
- Nut meal
- Adds body and a rich, tender crumb in place of much of the flour.
- Gluten or zwieback
- Provides dry structure that helps the cake hold its shape after folding.
- Lemon juice
- Adds acidity that stabilises the whipped egg whites and brightens the flavour.
The step that matters
Fold the yolk mixture into the egg whites. Folding gently keeps the air trapped in the whipped egg whites. Stirring or beating deflates the foam, leaving a dense, flat cake.

Fit is the average pairing score against malt, sugar, vanilla, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
