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 ↓
Simnel Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the butter until creamy.
Add the whipped egg whites and mix for 1 minute.
Incorporate the beaten egg yolks, sugar, flour, currants, candied citron, candied lemon peels, almonds, orange sugar, nutmeg, cinnamon, and allspice.
Pour in the brandy and a little water, then beat the mixture well.
Boil the cake
Gather the mixture into a lump, roll it out, and fold it over.
Place it in a cloth wrung out in hot water and floured, then tie it up.
Boil in a saucepan of boiling water for 3 hours.
Remove the cloth and place the cake smooth side up on a tin to cool.
Bake and cool
Brush the top with beaten egg and bake at 300°F (150°C) until the crust is hard and lightly browned.
Let the cake cool completely.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a tender crumb through fat.
- Egg whites
- Whipped to give lift and a light structure to the batter.
- Egg yolks
- Add richness, colour and binding to the batter.
- Flour
- Provides structure that holds the dense fruit and nuts together.
- Caster sugar
- Adds sweetness and helps tenderise the crumb.
- Currants
- Contribute sweetness, moisture and chewy fruit pieces throughout.
The step that matters
Boiling the cake in the cloth. The cloth must be wrung out in hot water and floured so the crust forms a firm skin and the cake does not stick. Tying it firmly keeps the shape and stops water entering, so the cake cooks evenly over the full 3 hours.
Swap the currant
How well each one fits the dish's main ingredients (butter, egg, sugar, flour, lemon, almond, orange):

Fit is the average pairing score against butter, egg, sugar, flour, lemon, almond, orange. Candidates are from the same food group and used in at least 100 recipes.
