To Frost Fruit

Ingredients

Directions

Prepare the fruit

  1. Select the finest plums, cherries, apricots, grapes, or small pears, leaving them on their stalks.

  2. Whisk the egg whites to a stiff froth.

  3. Dip the fruit in the beaten egg whites, leaving the stalks out.

Frost and dry

  1. Lift each piece of fruit one at a time and cover with finely powdered sugar.

  2. Cover a tray with white paper and lay the fruit on it.

  3. Place the tray in a cooling oven until the icing becomes firm.

Store

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg whites
Form a thin, glossy coating that the powdered sugar sticks to.
Finely powdered sugar
Forms a crisp, white icing that sets as the coating dries.

The step that matters

Drying the frosted fruit in the oven. Egg white must be whisked to a stiff froth and the oven kept cool so the icing sets firm and dry without browning or weeping. Heat that is too high can brown or cook the coating unevenly.

Swap the grape

How well each one fits the dish's main ingredients (plum, apricot, pear, egg, sugar):

  1. Vanillafits better
  2. Peachfits better
  3. Applefits better
  4. Grapethe original

Fit is the average pairing score against plum, apricot, pear, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
