Why it works: Rhubarb and lemon match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 546 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Rhubarb Tartlets
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the rhubarb
Wipe the rhubarb.
Cut the rhubarb into convenient lengths.
In a saucepan, combine rhubarb, lemon peel, lemon juice, a little water, and sugar. Stew gently.
Make and bake the pastry
Make short pastry.
Line buttered tartlet pans with pastry. Trim the edges of the pastry.
Fill the pastry with uncooked rice. Bake in a moderate oven (350°F/175°C).
Once tartlets are cooked, remove the rice.
Assemble and serve
Whisk the egg white with cream. Sweeten the mixture with loaf sugar. Chill the mixture if possible.
Fill the pastry with rhubarb. Top with cream.
Arrange tartlets on a hot dish. Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young rhubarb
- Provides the tart fruit filling that is sweetened and stewed into the tartlets.
- Egg white
- Whisked with cream to lighten the topping and give it a softer, airier set.
- Cream
- Adds richness and moisture to the whipped topping spooned over the tartlets.
- Short pastry
- Forms the crisp, buttery shell that holds the rhubarb filling.
- Sugar
- Sweetens the stewed rhubarb and balances its natural sourness.
The step that matters
Remove the rice after baking the pastry shells. Baking pastry blind with rice weights it so the shell keeps its shape and does not puff. The shells must be fully baked before the rice is removed, otherwise the pastry can collapse or stay soggy underneath the filling.
Swap the lemon
