Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Knead the dough until smooth and spongy.
Roll it out to ⅕ inch thick and cut with round, oval, or leaf-shaped cutters.
Prick each biscuit well and let them rest flat for 1-2 minutes.
Shape each biscuit into a cup with your thumb and drop into boiling water.
Keep the water boiling in a fish kettle or bain marie.
When the biscuits rise to the surface after about 1 minute, lift them out with a skimmer.
Transfer the biscuits to a pan of cold water and cover for 3-4 hours.
Drain well, brush with a little egg white, and place on buttered baking sheets.
Bake in a hot oven (400°F / 200°C) for about 12 minutes, ensuring they are thoroughly baked but not burnt.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
