French Charlotte

Ingredients

Directions

Prepare the cake shell

  1. Scoop out the center of the sponge cake, leaving 1 inch thick sides and bottom.

  2. Dip stale macaroons in orange juice and line the bottom of the cavity.

  3. Spread a thick layer of peach jam over the macaroons.

Make the cream filling

  1. Soak the gelatin in cold water, then dissolve it over hot water.

  2. Sweeten the thick cream with powdered sugar and add vanilla and dissolved gelatin.

  3. Whip the mixture to a solid froth and pour it into the cake mold.

Garnish

  1. Garnish with a border of candied cherries.

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

What each ingredient does

Sponge cake
Forms the sturdy outer shell that holds the filling in shape.
Stale macaroons
Soak up orange juice and add a dry, chewy layer under the jam.
Thick cream
Whipped into a light froth that gives the charlotte its airy, creamy filling.
Gelatine
Sets the whipped cream so the filling holds its shape when sliced.
Peach jam
Adds sweetness and fruit flavor and moistens the layer beneath it.

The step that matters

Whipping the gelatine cream. Gelatine must be fully dissolved before it is added to the cream, otherwise it forms lumps and will not set the filling evenly. The cream should be whipped to a firm froth so it holds air and keeps its shape once chilled.

Swap the orange

How well each one fits the dish's main ingredients (peach, cream, sugar, vanilla):

  1. Strawberryfits better
  2. Raspberryfits better
  3. Apricotfits better
  4. Orangethe original

Fit is the average pairing score against peach, cream, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
