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 base
In a saucepan, combine rhubarb and 8 ounces of powdered sugar, then stew gently until it forms a smooth pulp.
Increase the heat and stir often until reduced to a dry marmalade, then let it cool completely.
Make the meringue and bake
In a clean 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 preheated oven at 350°F (175°C) for about 30 minutes, until the center is firm and the top is lightly browned.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Cooks down into a dry marmalade that forms the tart's fruity base.
- Powdered sugar
- Sweetens the rhubarb and helps it break down into a smooth pulp.
- Egg whites
- Whisked to stiff peaks, they form the airy foam that becomes the meringue topping.
- Dry sifted sugar
- Folded into the whites to stabilise the foam and sweeten the meringue.
The step that matters
Let the rhubarb cool completely before spreading the meringue. Warm fruit melts the meringue's foam and makes it weep or slide, so the topping can lose its structure and fail to set properly in the oven.
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.
