Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Banana Tart
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 the filling
Rub the bananas through a sieve.
Mix the bananas with the grated rind and juice of the lemon and some flavored syrup.
Beat the eggs, then add the milk and cream, and stir into the banana mixture.
Bake
Line a dish with puff pastry.
Pour the mixture into the lined dish and bake at 350°F (175°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bananas
- Provide the main flavor and a soft, smooth body to the filling.
- Eggs
- Set the filling during baking, giving it a firm, sliceable texture.
- Milk
- Adds moisture and softness, diluting the filling so it bakes creamy.
- Cream
- Adds richness and fat, giving the filling a smoother, silkier mouthfeel.
- Puff pastry
- Forms the crisp, flaky base that holds the filling.
The step that matters
Bake until set. Eggs set as their proteins coagulate with heat. Underbaking leaves a runny center, while overbaking can make the filling dry and grainy or cause it to crack.
Swap the lemon

Fit is the average pairing score against banana, milk, sugar, syrup, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
