Why it works: Flour and almond 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 ↓

Ingredients
Directions
The book says “a medium oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the paste
In a saucepan, bring the butter, water, and sugar to a boil.
Stir in the flour and let it simmer for 10 minutes, stirring occasionally.
When nearly cold, add the eggs one at a time, stirring well after each addition.
Shape and bake
Drop small spoonfuls of the mixture onto a greased baking sheet.
Bake in a moderate oven at 350°F (175°C) for 20 minutes.
Egg wash the tops.
Cover with chopped almonds.
Fill and serve
Fill between two halves with whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Add structure and help the loaves rise and set as they bake.
- Flour
- Forms the starch framework that gives the loaves their structure.
- Butter
- Adds fat for a tender texture and rich flavour.
- Caster sugar
- Adds sweetness and helps the tops brown in the oven.
- Whipped cream
- Fills the loaves, adding moisture and a light, rich texture.
The step that matters
Cool the paste before adding the eggs. If the paste is too hot, the eggs can scramble instead of blending in. Adding them one at a time and stirring well after each creates a smooth, glossy mixture that holds its shape and rises properly in the oven.
