Why it works: Rhubarb and ginger work together. They rank in the top 7% of all ingredient pairs, and cooks put them together in 241 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Pillau, East Indian Rhubarb Turnovers
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the turnovers
Make a good pastry.
Roll it out to ¼ inch thick.
Cut rounds 4 to 6 inches in diameter.
Place rhubarb on half of each round.
Add sugar.
Sprinkle with ginger.
Fold the pastry over.
Pinch edges tightly.
Glaze and bake
Brush with egg white.
Sprinkle with powdered sugar.
Bake on a baking sheet at 400°F (200°C) for about 20 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pastry
- Forms the flaky case that encloses the filling and browns in the oven.
- Young rhubarb
- Provides the tart fruit filling that the sugar balances.
- Sugar
- Sweetens the tart rhubarb and helps it caramelise slightly as it bakes.
- Powdered ginger
- Adds warm, aromatic spice that complements the rhubarb.
- Egg white
- Gives the surface a glossy sheen and helps the powdered sugar stick.
The step that matters
Pinch edges tightly. A poorly sealed edge lets juice escape during baking, so the filling leaks out and the turnover can burst or empty. Firm pinching fuses the pastry layers so the steam and juices stay inside.
Swap the ginger
How well each one fits the dish's main ingredients (rhubarb, sugar, egg):
- Cinnamonfits better
- Nutmegfits better
- Capersfits about as well
- Gingerthe original
Fit is the average pairing score against rhubarb, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
