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 ↓
Rhubarb Sherbet
Ingredients
Directions
Prepare the fruit
Stew the rhubarb until very tender and press through a sieve to measure the pulp.
Add sugar to taste and heat over the fire.
Dissolve the gelatine in a little cold water, then add it to the fruit mixture.
Once the sugar is dissolved, remove from heat and let it cool.
Freeze and serve
Pour the mixture into a chilled freezer and freeze slowly for 5 to 6 minutes.
Fold in the stiffly beaten egg whites and powdered sugar.
Continue freezing until smooth and firm, then serve in sherbet glasses garnished with chopped candied cherries.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb pulp
- Provides the main fruit flavour and tart base of the sherbet.
- Gelatine
- Sets the mixture so the frozen sherbet holds a smooth, firm body.
- Sugar
- Sweetens the tart rhubarb and lowers the freezing point for a softer texture.
- Egg whites
- Whipped in as foam, they add lightness and an airy, smooth texture.
- Powdered sugar
- Dissolves easily into the beaten whites, sweetening and stabilising the foam.
The step that matters
Folding in the beaten egg whites. Whites must be stiffly beaten and folded gently so the air bubbles stay intact. Deflating the foam through vigorous stirring makes the sherbet dense rather than light.
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.
