Why it works: Orange and cinnamon match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 3,437 recipes mention both. Both carry guaiacol, which smells smoky, sweet. The science ↓
The recipe
Ingredients
Contains: egg, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: biscuits
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Beat the whites and yolks of the eggs until they form a solid froth.
Add the orange flower, rose, or laurel water, cinnamon, and powdered sugar.
Mix in enough potato flour to form a paste.
Shape and bake
Roll out the paste thinly and stamp into fanciful biscuit shapes.
Place the biscuits on greased paper and bake in a moderate oven (350°F / 175°C) until done.
Glaze and set
Once cooled, glaze the biscuits and return them to the oven for a short time to set.

Cinnamon and sugar share little aroma chemistry, yet 30,777 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped to a froth, they give the paste lift and an airy, light structure.
- Powdered loaf sugar
- Adds sweetness and bulk to the paste, helping it hold its shape when stamped.
- Cinnamon
- Provides the main aroma and warm flavour of the biscuits.
- Potato flour
- Binds the mixture into a workable paste that can be rolled and stamped.
The step that matters
Beating the eggs to a solid froth. The whipped eggs are the only lift in this paste, so under-beating leaves dense biscuits. Whipping incorporates air that expands slightly in the oven and sets the structure.
Flavor stand-ins for the potato
How well each one fits the dish's main ingredients (egg, orange, cinnamon, sugar, flour):

- Arrowrootbetter flavor fit
- Capsicumbetter flavor fit
- Potatothe original
Fit is the average pairing score against egg, orange, cinnamon, sugar, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
