Why it works: Rhubarb and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 1,852 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
A Meringue of Rhubarb, or Green Gooseberries
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.
Make the rhubarb filling
In a saucepan, combine rhubarb and 8 ounces of sugar.
Cook gently until it forms a smooth pulp.
Increase the heat and stir often until it reduces to a thick, dry marmalade.
Let it cool completely.
Make the meringue and bake
In a mixing bowl, whisk the egg whites until they form stiff peaks.
Gently fold in 4 tablespoons of dry sifted sugar until well combined.
Spread the meringue over the cooled rhubarb in a deep tart dish.
Bake in a 350°F (175°C) oven for about 30 minutes, ensuring the center is firm and the top is lightly browned.

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, once reduced, the thick base for the tart.
- Sugar
- Sweetens the rhubarb and helps it reduce to a thick, dry marmalade.
- Egg whites
- Whisked into stiff peaks to form the airy meringue topping.
- Dry sifted sugar
- Stabilises the whisked egg whites and sweetens the meringue topping.
The step that matters
Cooling the rhubarb completely before adding the meringue. Spreading meringue over warm rhubarb can make it weep and soften, since heat thins the foam. Letting the marmalade cool fully keeps the topping stable and the layers distinct when baked.
Swap the rhubarb
How well each one fits the dish's main ingredients (sugar, egg):
- Cinnamonfits better
- Nutmegfits better
- Rhubarbthe original
- Gingerfits about as well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
