Arrowroot Charlotte

Ingredients

Directions

Prepare

  1. Slice the sponge cakes thinly.

  2. Line the bottom and sides of a mold with the sliced cakes.

Make the custard

  1. Mix the baked flour and arrowroot with enough cold milk to form a smooth paste.

  2. Heat the pint of milk in a saucepan with the isinglass.

  3. Stir in the paste just before the milk boils.

  4. Boil for a few minutes while stirring continuously.

  5. Pour the mixture into the mold while hot.

Set and serve

  1. Once cooled, turn the Charlotte out of the mold.

  2. Dust with powdered sugar.

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

What each ingredient does

Sponge cakes
Form the lining and structure around the set filling.
Baked flour
Thickens the milk so it becomes a firm, spoonable custard.
Baked arrowroot
Adds starch that thickens the milk into a smooth, glossy filling.
Milk
Forms the liquid base that the thickeners and isinglass set.
Isinglass
Sets the milk as it cools, giving the filling a firm, sliceable body.

The step that matters

Stir the paste in and keep stirring as the milk boils. Starch mixed into hot liquid can clump if added unevenly. Stirring constantly while it heats and boils spreads the thickener evenly, so the custard turns smooth rather than lumpy.
