Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the Nuns' Cakes paste.
Form small balls and place them on greased thin iron plates or tins, spaced apart.
Brush the balls with egg yolks.
Bake in a moderately hot oven at 350°F (175°C).
A moment before they are fully cooked, remove them from the oven and sprinkle with powdered sugar.
Return them to the oven to glaze beautifully.
