Soda Popcorn Flake

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the sugar base

  1. In a large pot, combine sugar, glucose, and water.

  2. Cook the mixture until it reaches 300°F (150°C).

Add the popcorn

  1. Remove from heat and add popcorn and soda.

  2. Mix thoroughly and place the pot on a warm surface to keep the mixture warm.

Spread and break

  1. Pour the mixture onto a slab and spread it as thin as possible.

  2. Once cooled, break into small pieces.

What each ingredient does

Sugar
Forms the glassy, crisp matrix that holds the flakes together as it cools.
Glucose
Inhibits sugar crystallization, keeping the set texture smooth rather than grainy.
Popcorn
Provides the light, airy body and crunch of the finished flake.

The step that matters

Cooking to 300°F (150°C). The final temperature controls the hardness of the cooled sugar. Stopping early leaves the flake sticky and soft, while overheating can make it taste bitter or burnt.
