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
Combine rhubarb and powdered sugar in a saucepan.
Stew gently until it forms a smooth pulp.
Increase heat and stir often until it reduces to a dry marmalade.
Let it cool completely.
Make the meringue and bake
Whisk egg whites until they form stiff peaks.
Fold in dry sifted sugar until fully 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 light brown and crisp.

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 into stiff peaks to form the airy meringue topping that sets in the oven.
- Dry sifted sugar
- Folded into the whites to stabilise the meringue and give it a crisp, browned top.
The step that matters
Reducing the rhubarb to a dry marmalade. If the rhubarb stays wet, it releases liquid under the meringue and can make the base soggy. Cooling it completely before spreading the meringue keeps the topping from collapsing or weeping.
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.
