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 (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the rhubarb
Stew the rhubarb with sugar gently over low heat.
Make and bake the shells
Prepare short pastry.
Line buttered tartlet pans, trimming the edges.
Fill the pastry with uncooked rice.
Bake in a 350°F (175°C) oven until golden.
Remove the rice from the baked tartlets.
Make the cream and assemble
Whisk the egg white with cream.
Rub loaf sugar on lemon zest and sweeten the mixture until frothy, ideally over ice.
Fill each tartlet with stewed rhubarb.
Top each tartlet with the whipped cream mixture.
Serve
Serve on a hot dish covered with a napkin or fancy paper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the tart flavour and soft filling once stewed with sugar.
- Sugar
- Sweetens the rhubarb and helps it break down into a soft stewed filling.
- Cream
- Whipped with egg white to form a light, airy topping for the tartlets.
- Egg white
- Whisked with cream to help trap air and create a frothy topping.
- Short pastry
- Forms the crisp, buttery shell that holds the rhubarb filling.
The step that matters
Sweetening the cream until frothy. Whisking the egg white and cream together traps air into a foam. Overbeating can cause the cream to turn grainy or separate, so it should be whipped only until frothy and kept cool, ideally over ice.
