Why it works: Cinnamon and flour 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 ↓

Hermit Cookies

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Preheat your oven to 350°F (175°C).
In a bowl, beat the eggs and mix in the brown sugar and softened butter.
Dissolve the baking soda in a little milk and add it to the mixture.
Stir in the currants and cinnamon.
Gradually add flour until the dough is firm enough to roll.
Roll out the dough and cut into desired shapes.
Place on a baking sheet and bake for about 10-12 minutes or until golden.

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.
