How To Store Banana Walnut Brittle Properly

  • Room Temperature Love: Store the brittle at consistent room temperature between 60-70°F. Avoid refrigeration, which introduces dampness and can make the candy lose its delightful texture.

Description

Creamy banana walnut brittle delights dessert enthusiasts with its rich caramelized flavors. Sweet and crunchy layers blend perfectly for an indulgent treat that satisfies classic comfort cravings.


Ingredients

Scale
  • 1 cup (200 g/7.05 oz) granulated sugar
  • 1 cup (100 g/3.53 oz) walnuts, chopped and toasted
  • ½ cup (120 g/4.23 oz) freeze-dried banana slices, crumbled
  • ½ cup (120 ml/4 fl oz) light corn syrup
  • ¼ cup (60 ml/2 fl oz) water
  • 2 tbsps (30 g/1.06 oz) unsalted butter
  • ½ tsp baking soda
  • ½ tsp vanilla extract

Instructions

  1. Preparation: Line a baking sheet with parchment paper or silicone mat, creating a non-stick surface for the brittle.
  2. Walnut Roasting: Toast walnuts in a dry skillet over medium heat, stirring gently until fragrant and golden, releasing their rich, nutty essence.
  3. Caramel Formation: Merge sugar, corn syrup, and water in a heavy-bottomed saucepan. Heat gently, dissolving sugar completely, then escalate to a rolling boil without additional stirring.
  4. Temperature Control: Utilize a candy thermometer to track the sugar mixture, aiming for the hard-crack stage at 300°F, signaling optimal caramelization.
  5. Flavor Infusion: Remove from heat, rapidly incorporate butter, triggering intense bubbling. Quickly introduce baking soda and vanilla extract to elevate taste and texture.
  6. Ingredient Integration: Fold freeze-dried banana fragments and pre-toasted walnuts into the molten caramel, ensuring comprehensive coating with the golden syrup.
  7. Spreading Technique: Pour the blazing mixture onto the prepared baking sheet, using a spatula to distribute evenly and thinly before solidification begins.
  8. Cooling and Fragmenting: Allow the brittle to cool completely at room temperature for approximately 30 minutes. Once hardened, break into irregular, rustic pieces.
  9. Storage: Transfer brittle fragments to an airtight container, preserving their crisp texture and complex flavor profile for up to two weeks at room temperature.

Notes

  • Prevent Sugar Crystallization: Avoid stirring the caramel once it starts boiling to prevent sugar crystals from forming, which can make the brittle grainy.
  • Maintain Precise Temperature: Use a reliable candy thermometer to accurately reach the 300°F hard-crack stage, as even a few degrees can dramatically change the brittle’s texture.
  • Work Quickly When Adding Ingredients: Have all ingredients measured and ready before starting, as the caramel mixture sets rapidly and requires immediate incorporation of butter, baking soda, and add-ins.
  • Store Carefully to Preserve Crispness: Keep the brittle in a completely dry, airtight container away from humidity to maintain its signature crisp texture and prevent softening.
