  2. Roll it out to ¼ inch thick.

  3. Cut rounds 4 to 6 inches in diameter.

  4. Place rhubarb on half of each round.

  5. Add sugar.

  6. Sprinkle with ginger.

  7. Fold the pastry over.

  8. Pinch edges tightly.

Glaze and bake

  1. Brush with egg white.

  2. Sprinkle with powdered sugar.

  3. Bake on a baking sheet at 400°F (200°C) for about 20 minutes.

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):

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Capersfits about as well
  4. 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.
