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 ↓
Nut Squares
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the eggs until light.
Add the brown sugar and beat for 2 minutes.
Sift together the flour, cinnamon, salt, and baking powder.
Add the sifted mixture to the egg mixture along with the nutmeats.
Bake and cut
Place the dough in a greased and flour-dusted pan.
Bake in a moderate oven at 350°F (175°C) until done.
Remove from the oven and cut into squares.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 recipes: they 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
- Provide structure and moisture, and bind the batter together as it bakes.
- Brown sugar
- Adds sweetness, moisture and a chewy, soft texture to the squares.
- Flour
- Forms the structure that holds the squares together once baked.
- Baking powder
- Releases gas in the batter, helping the squares rise and become lighter.
- Nutmeats
- Add crunch and a nutty flavour that contrasts with the soft crumb.
- Cinnamon
- Adds warm aroma and spice to the sweet batter.
The step that matters
Bake until done. The centre must fully set while the outside is not overbrowned. Underbaked batter stays wet and gummy, while overbaking dries the squares and makes them crumbly.
Swap the cinnamon

- Nutmegfits about as well
- Capersfits less well
Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
