Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Orange Wafers
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Preheat the oven to 400°F (200°C).
Beat the egg whites and yolks separately until very light.
Mix the sugar, flour, lemon zest, lemon juice, and baking powder into the egg mixture.
Drop spoonfuls of the batter onto buttered parchment paper.
Bake and fill
Bake until lightly golden.
Spread the under side of each wafer with orange marmalade and sandwich two together.
Make and spread the icing
For icing, boil the granulated sugar and water until it forms threads.
Slowly pour the syrup into the beaten egg white while continuously beating.
Spread the icing on the wafers while warm.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Whipped to trap air, giving the wafers lift and a light, delicate crumb.
- Flour
- Provides the structure that holds the wafers together once baked.
- Baking powder
- Releases gas in the batter, helping the wafers rise and stay tender.
- Sugar
- Adds sweetness and helps the wafers brown lightly in the oven.
- Orange marmalade
- Adds sweet, bitter citrus flavour and moisture where the wafers are sandwiched.
The step that matters
Pouring the syrup into the egg white. The syrup must be poured slowly while beating continuously. Hot syrup added too fast can cook the egg white unevenly and deflate the foam, while steady beating lets the syrup blend into a smooth, stable icing.
Swap the orange
How well each one fits the dish's main ingredients (sugar, flour, egg, lemon):
- Raisinfits better
- Vanillafits better
- Orangethe original
- Blueberryfits about as well
Fit is the average pairing score against sugar, flour, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
