Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Naples' Biscuits
Ingredients
Directions
Make the batter
In a saucepan, combine water, orange flower water, and sugar; boil until sugar melts.
Pour the syrup into the beaten eggs while stirring quickly.
Beat the mixture until cold, then stir in the flour.
Bake
Prepare paper moulds for the biscuits and pour the batter into them.
Place the moulds on baking tins and dust with fine sugar before baking.
Watch closely while baking to prevent scorching.

Egg and flour 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
- Beaten eggs provide structure and richness, setting the batter as it bakes.
- Flour
- Gives the batter body and structure so the biscuits hold their shape.
- Fine sugar
- Sweetens the batter and, dusted on top, helps the biscuits brown.
The step that matters
Watch closely while baking. Sugar browns and scorches quickly in an oven, so the biscuits can turn bitter before they are cooked through. Checking them during baking prevents this.
Swap the orange
How well each one fits the dish's main ingredients (sugar, egg, flour):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
