Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Orange Tartlets
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Cream the butter and sugar together until light and fluffy.
Beat in each egg yolk one at a time.
Mix the grated orange peel, cornflour, and orange juice together, then add to the mixture.
Fold in the cake crumbs and the stiffly whipped egg whites.
Bake and finish
Pour the mixture into 10 to 12 tartlet tins lined with short pastry.
Bake in a moderate oven at 350°F (175°C) for about 20 minutes.
Allow to cool before icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the tartlets a rich, tender body.
- Eggs
- Yolks enrich the batter, and whipped whites lighten it and help it rise and set.
- Cake crumbs
- Add body and softness to the filling as they absorb moisture from the batter.
- Cornflour
- Thickens the orange juice and rind mixture so the filling sets smoothly when baked.
- Castor sugar
- Sweetens the filling and helps create a light, aerated creamed base.
The step that matters
Folding in the whipped egg whites. Egg whites hold air only when whipped stiff and gently folded in; overmixing or deflating them makes the tartlets dense instead of light.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, egg):
- Vanillafits better
- Lemonfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
