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 ↓
Rum Rings
Ingredients
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.
Make the dough
Sift the flour and mix thoroughly with the butter and crumbled egg yolks.
Add the caster sugar and Kirsch (or rum), then mix in enough milk to form a stiff dough.
Roll out the dough thinly and cut into rings.
Bake
Place the rings on a buttered baking sheet, brush with sweetened milk, and sprinkle with grated almonds.
Bake in a moderate oven at 350°F (175°C) until done, checking for doneness based on thickness and size.

Flour and butter 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
- All-purpose flour
- Provides the structure that holds the stiff dough together after baking.
- Butter
- Adds fat that makes the dough rich and tender rather than tough.
- Hard-boiled egg yolks
- Add richness and fat, helping the dough bake tender and crumbly.
- Caster sugar
- Sweetens the dough and promotes light browning in the oven.
- Kirsch or rum
- Adds aroma and flavor characteristic of the dish.
The step that matters
Judging doneness. Rings vary in thickness and size, so baking time changes. Underbaked rings stay soft and pale, while overbaked ones turn dry and dark, so check color and firmness rather than relying on the clock.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
