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 Meringue Tarts
Ingredients
Directions
Prepare the filling
Peel the rhubarb.
Cut the rhubarb into pieces about 1 inch long.
Place the rhubarb in a covered jar with a little water.
Set the jar in the oven until the juice is drawn out.
Add the beaten egg yolks, lemon rind, and moist sugar to the rhubarb.
If the rhubarb is very juicy, pour off some of the juice.
Bake and top with meringue
Line two tart pans with pastry.
Fill the lined pans with the rhubarb mixture.
Bake until the tarts are a delicate brown.
Whip the egg whites to stiff peaks.
Add the pounded sugar and vanilla flavoring to the whipped whites.
Pile the meringue lightly on top of the tarts.
Return the tarts to the oven to lightly brown the meringue.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the tart acidity and the bulk of the filling, releasing juice as it cooks.
- Eggs
- Egg yolks enrich and thicken the filling, while whipped whites form the light meringue topping.
- Moist sugar
- Sweetens the rhubarb and draws out its juice, balancing its tartness.
- Pounded white sugar
- Dissolves into the whipped whites to stabilise the meringue and give it a glossy, sweet finish.
The step that matters
Whipping the egg whites to stiff peaks. Whites must be whipped until they hold stiff peaks and be free of yolk, since fat prevents foam from forming properly. Stiff whites hold their shape on the tarts and brown evenly in the oven.
Swap the vanilla
The recipe marks vanilla as optional. How well each one fits the dish's main ingredients (rhubarb, lemon, egg, sugar):
- Vanillathe original
- Orangefits about as well
- Limefits less well
- Blueberryfits less well
Fit is the average pairing score against rhubarb, lemon, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
