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 ↓
A Large Rich Two-guinea Cake
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 batter
Preheat your oven to 400°F (200°C).
In a large bowl, rub the softened butter until fine.
In another bowl, whisk the eggs for 10 minutes.
Over a gentle heat, combine the whisked eggs and powdered sugar until warm, then remove from heat and whisk until cool.
Mix the egg and sugar mixture with the butter using your hands.
Add the ground mace, ground cinnamon, and brandy to the mixture.
Fold in the chopped lemon and orange peel, citron, and sweet almonds.
Gradually add half of the sifted flour, then fold in the currants.
In a separate bowl, mix the pounded bitter almonds with a little powdered sugar to prevent oiling, then add to the mixture.
Finally, fold in the remaining flour until well combined.
Bake
Line a large cake pan with parchment paper, placing four sheets inside and at the bottom.
Pour the batter into the prepared pan and bake in the preheated oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Unsalted butter
- Creams with sugar to trap air and give the cake a rich, tender crumb.
- Eggs
- Provide structure and moisture as they set during baking.
- Powdered sugar
- Sweetens the batter and helps create a fine, even texture when creamed.
- All-purpose flour
- Forms the main structure of the cake as its proteins set during baking.
- Currants
- Add chewy sweetness and fruity bites throughout the cake.
- Mixed lemon and orange peel
- Adds aromatic citrus flavor and a bright, slightly bitter note.
The step that matters
Whisking the eggs and sugar over gentle heat. Warming the eggs and sugar gently helps the sugar dissolve and the batter emulsify smoothly. Overheating can scramble the eggs, leaving lumps and an uneven texture in the finished cake.
Swap the mace
How well each one fits the dish's main ingredients (butter, egg, sugar, cinnamon, brandy, lemon, orange):
- Nutmegfits better
- Cardamomfits better
- Allspicefits better
- Macethe original
Fit is the average pairing score against butter, egg, sugar, cinnamon, brandy, lemon, orange. Candidates are from the same food group and used in at least 100 recipes.
