Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, mix flour, orange zest, baking soda, and salt.
Work the mixture with your hands on a clean surface until it becomes elastic.
Cover the dough and let it rest in a cool place for 2 hours.
Shape and boil
Divide the dough into small ropes, each 2 inches long.
Wet the edges and form the ropes into rings.
Carefully drop the rings into boiling water.
Boil gently until they float to the top.
Remove them with a skimmer and place them in cold water for 2 hours.
Bake
Drain the rings and place them on a baking sheet.
Lightly brush with egg and bake in a 400°F (200°C) oven until golden.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Flour
- Forms the main structure of the dough so the rings hold their shape.
- Eggs
- Brushed on top to promote browning and a golden finish.
- Baking soda
- Reacts with the dough to help it rise and lighten during baking.
- Orange zest
- Adds aromatic citrus flavor to the dough.
The step that matters
Boil gently until they float to the top. Boiling vigorously can tear the delicate rings and knock them out of shape. Gentle simmering lets the dough set while keeping the rings intact before they are baked.
