Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Meringue Custard Tartlets
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat oven to 350°F (175°C).
Butter deep individual pie-tins or fluted tartlet pans (about 6 inches in diameter and 2-3 inches deep).
Line the pans with puff pastry.
Make the custard
In a bowl, stir the beaten yolks of 6 eggs with 2 tablespoons flour, ¼ teaspoon salt, and ½ cup cream until smooth.
Heat the mixture in a saucepan, stirring until it thickens and coats the spoon without boiling.
Remove from heat, add a few drops vanilla extract, and let cool.
Fill the lined molds with custard and bake in preheated oven.
Make the meringue and finish
In a copper bowl, beat egg whites until frothy, then gradually add ½ pound sugar and a dash salt until firm.
Spread a thin layer of meringue over the tart and decorate with remaining meringue using a piping bag.
Sprinkle powdered sugar on top and return to oven until lightly golden.
Remove from oven, let cool, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set on heating, giving it a rich, smooth body.
- Flour
- Stabilises the custard so it thickens without curdling during heating.
- Cream
- Adds fat and richness, giving the custard a softer, silkier texture.
- Egg whites
- Whipped to foam, they form the airy structure of the meringue topping.
- Sugar
- Stabilises the whipped whites and gives the meringue sweetness and a crisp, golden finish.
The step that matters
Heating the custard without boiling. Egg yolks thicken as their proteins set with gentle heat. If the mixture boils, the yolks can scramble and curdle, leaving a grainy custard instead of a smooth one.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, flour, cream, sugar):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, flour, cream, sugar. Candidates are from the same food group and used in at least 100 recipes.
