Why it works: Flour and cinnamon are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 17,341 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a rather quick 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).
Break the egg into a bowl and mix with sour milk.
Add baking soda and brown sugar, then mix well.
Stir in the flour and cinnamon until combined.
Bake until golden brown and serve warm.
