Arrowroot Fueling

Ingredients

Directions

Prepare the mold

  1. Cut the sponge cakes into thin slices and sprinkle with flavoring.

  2. Line a plain mold with the cake slices.

  3. Soak the isinglass in milk for 2 hours.

Make the pudding

  1. In a saucepan, boil the milk, sugar, and arrowroot (rubbed smooth in a little milk) along with the soaked isinglass.

  2. Beat the egg whites to a froth.

  3. Once the mixture reaches boiling point, add the egg whites and boil until thick, stirring constantly.

  4. Pour the mixture into the wet mold.

Finish and serve

  1. Make a custard with the egg yolks and pour it around the pudding before serving.

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

What each ingredient does

Arrowroot
Thickens the milk into a smooth, set pudding texture.
Eggs
Egg whites add airy lightness when beaten and stirred in; yolks enrich the custard.
Isinglass
Gelatin-like setting agent that helps the pudding firm up when cooled.
Sponge cakes
Form the structure of the mold and soak up the flavoring.

The step that matters

Boiling the mixture until thick after adding the egg whites. Stirring constantly prevents the arrowroot and egg whites from scorching or lumping, and boiling thickens the starch so the pudding sets properly when cooled.

Swap the arrowroot

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

  1. Sweet potatofits better
  2. Capsicumfits better
  3. Asparagusfits better
  4. Arrowrootthe original

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