Why it works: Sugar and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 98,233 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Orange Tarts
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.
Prepare the peel
Grate the zest of the Seville orange.
Squeeze the juice into a dish.
Soak the peel in water, changing it often for four days.
Boil the peel in a saucepan of water, changing the water twice to remove bitterness.
Once tender, wipe the peel.
Mash the peel in a mortar.
Make the filling
Boil the same weight of sugar in water to make a syrup.
Skim the syrup.
Add the mashed peel to the syrup and boil until clear.
Let the mixture cool.
Bake and serve
Fill the tarts with the mixture and add the orange juice.
Bake in a preheated oven at 400°F (200°C) until golden.

Orange and sugar barely smell alike, yet cooks put them together in 19,212 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
- Seville orange
- Provides the bitter peel and juice that flavour the filling.
- Double refined sugar
- Sweetens the filling and, boiled into syrup, helps set it clear and thick.
- Puff pastry
- Forms the flaky case that holds the filling while it bakes.
- Butter
- Adds richness and helps the pastry brown and taste savoury-sweet.
The step that matters
Boil the peel until clear, after changing the water. Repeated water changes draw out bitter compounds from the peel. Boiling the peel in sugar syrup until clear cooks it through so the filling is tender and sets evenly.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter):
- Vanillafits better
- Figfits better
- Peachfits better
- Orangethe original
Fit is the average pairing score against sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
