Why it works: Vanilla and sugar are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Savoy and Sponge Biscuits
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Preheat the oven to 400°F (200°C).
Whisk the egg whites to stiff peaks.
Mix one-third of the egg whites into the yolks with vanilla until smooth.
Gently fold in the remaining egg whites until well combined.
Pipe the mixture onto stiff paper in 4-inch lengths.
Dust with fine sugar through a sieve.
Shake off excess sugar and place on plates.
Bake in the preheated oven until golden.
Use a flat knife to remove biscuits from paper.
