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 ↓
English Brioche, and Brioche-rusks
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make and shape the dough
Mix 1 pound of flour with 1 tablespoon of water or cream and let it rise until doubled in size.
Shape the dough into small brioche shapes or roll it thick and cut into rusks with a round cutter.
Bake and dry
Brush the tops with beaten egg and bake in a preheated oven at 400°F (200°C) for 10 to 15 minutes until well baked and golden.
Divide the rusks and return them to the oven at a lower heat until very crisp and evenly browned.

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 gluten network that gives the dough its structure and lets it hold a rise.
- Egg
- Brushed on top, it promotes browning and a glossy golden colour during baking.
The step that matters
Returning the rusks to the oven at a lower heat. Rusks must be dried out fully to become crisp. Baking at too high a heat can brown the outside before the centre loses its moisture, leaving them soft inside.
