Why it works: Orange and lemon 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 ↓
Sweetmeat Biscuits
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the biscuits
Cut the baked Naples biscuits into 1.5-inch squares and 1-inch thick pieces.
Place them on a wire rack and crisp them in a 400°F (200°C) oven.
Ice and decorate
In a bowl, mix the egg whites, sugar, and orange flower water to make icing.
Dip one side of each biscuit into the icing.
Chop the sweetmeats into small pieces and sprinkle them over the iced side of the biscuits.
Harden and serve
Return the biscuits to the wire rack and place them back in the oven to harden the icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Naples biscuits
- Form the crisp, dry base that holds the icing and sweetmeats.
- Egg whites
- Whip-free binder that forms the icing and sets to a firm, glossy coating when baked.
- Sugar
- Sweetens the icing and helps it harden into a crisp, glossy layer.
- Sweetmeats
- Add chewy texture and concentrated candied citrus flavor on the iced surface.
The step that matters
Hardening the icing in the oven. Egg white and sugar set into a firm coating only with gentle, dry heat. Too much heat can brown or weep the icing, while too little leaves it tacky, so the biscuits should be watched closely while they harden.
Swap the orange
How well each one fits the dish's main ingredients (biscuit, egg, sugar, lemon):
- Vanillafits about as well
- Orangethe original
- Blueberryfits about as well
- Limefits about as well
Fit is the average pairing score against biscuit, egg, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
