Why it works: Almond and flour are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Irish Cake
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.
Make the batter
Beat the butter to a cream.
Sift in the hot sugar and mix well.
Add the yolks of the eggs, then fold in the beaten egg whites.
Work the mixture for 1 hour, then gradually add the flour.
Once thoroughly mixed, stir in the brandy.
Just before baking, fold in the currants, almonds, and lemon or citron peel.
Bake
Pour the batter into a prepared cake pan and bake in a hot oven at 400°F (200°C) for about 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar, it traps air that helps the cake rise and gives a tender crumb.
- Eggs
- Egg whites add lift and structure, while yolks add richness and help bind the batter.
- Flour
- Provides the structure that sets the cake as the proteins bake and firm up.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a light, aerated batter.
- Almonds
- Add crunch and a nutty flavour, and contribute fat that keeps the cake moist.
- Currants
- Add chewy pockets of sweetness and moisture throughout the cake.
The step that matters
Folding in the beaten egg whites. Whites must be folded gently so the air bubbles they hold are not deflated. Those bubbles help the cake rise and keep its texture light.
