  • Fluff Not Thickening: Ensure your syrup reached the right temperature. Using a candy thermometer is crucial.
  • Grainy or Crystallized Fluff: This can happen if the sugar wasn’t dissolved completely. Always ensure the syrup is clear before proceeding.
  • Too Runny or Too Stiff: Adjust the beating time. Overbeating can make it too stiff, while underbeating can leave it runny.

How to Use Marshmallow Fluff

Marshmallow fluff isn’t just for spreading! You can use your homemade fluff in any recipe that calls for marshmallow fluff, but also think about layering it in parfaits, swirling into homemade ice creams, or even using it as a unique filling for donuts or cupcakes!

Tips From the Chef

  • Always use a candy thermometer when boiling your syrup to ensure the right consistency.
  • If your aim is more of a sauce than a shaped fluff, heat the corn syrup only to 230 degrees Fahrenheit.
  • Ensure your egg whites are at room temperature for optimal fluffiness.
  • Slowly pouring the hot syrup into the whipped egg whites is key to achieving the desired texture.

Safety Tip

Working with hot syrups requires caution. Always use heat-resistant utensils, be aware of potential splatters, and keep your workspace free from distractions.

Storage Instructions

Store your homemade marshmallow fluff in an airtight container at room temperature for up to 2 weeks. If refrigerated and it becomes too stiff, gently warm in a microwave for a few seconds to regain its spreadability. Freezing isn’t recommended due to potential texture changes. Stir well before use.
