Make this simple seed brittle recipe for a crunchy, gluten free snack. This guide provides straightforward instructions for creating crystallized seed candy perfect for gifting or snacking.
Lightly grease a large baking sheet or line it with parchment paper. Set aside.
Combine the seeds, sugar, corn syrup, and water in a heavy-bottomed saucepan. Stir gently over medium heat until the sugar dissolves.
Stop stirring once the mixture boils. Insert a candy thermometer.
Cook the mixture without stirring until it reaches 300 degrees Fahrenheit (hard crack stage). This usually takes 15 to 20 minutes. Watch the temperature closely.
Remove the saucepan from the heat immediately when it reaches 300 degrees Fahrenheit.
Quickly stir in the butter, vanilla extract, and baking soda. The mixture will foam up rapidly. Stir only until just combined.
Immediately pour the hot mixture onto the prepared baking sheet. Do not spread it with a spatula; let it flow naturally.
Allow the brittle to cool completely, about 30 minutes, until hard.
Break the cooled brittle into irregular pieces. Store in an airtight container.
Notes
For a nut free brittle, ensure your seed sources are not cross-contaminated with nuts.
If the brittle feels sticky after cooling, the temperature did not reach 300 degrees Fahrenheit. Reheat and cook longer next time.
You can roast the seeds lightly before starting to deepen their flavor.
This recipe works well as a vegan seed candy if you use plant-based butter.
