Why it works: Rhubarb and vanilla match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 276 recipes. Both carry methyl cinnamate, which smells strawberry. The science ↓
Rhubarb Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Stew the rhubarb until tender.
Add the grated rind and juice of the lemon, beaten egg yolks, and sugar.
Bake the pie
Line a pie tin with the crust and fill it with the rhubarb mixture.
Bake at 400°F (200°C) until the crust is golden brown.
Top with meringue
Beat the egg whites to a stiff froth, adding powdered sugar and vanilla.
Spread the meringue over the top of the pie.
Return to the oven until the meringue is light brown.

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 bulk that makes up the filling.
- Eggs
- Egg yolks thicken the filling, while whites whip into the meringue topping.
- White sugar
- Sweetens the tart rhubarb and helps balance its acidity.
- Lemon
- Adds bright acidity and aroma that lift the rhubarb flavour.
- Powdered sugar
- Dissolves easily into the egg whites, sweetening and stabilising the meringue.
The step that matters
Beat the egg whites to a stiff froth. Egg whites must be whipped until stiff so they hold air and form a stable meringue. Under-whipped whites slump and weep, and over-browning in the oven can make the topping collapse or turn tough.
