Step 1

Whisk egg white in a medium bowl until frothy. Mix in cashews until coated. Let soak for 30 minutes.

Step 2

Preheat oven to 250 degrees F (120 degrees C). Line a baking sheet with aluminum foil.

Step 3

Combine sugar, cumin, salt, and cayenne pepper in a small bowl. Pour over cashews and toss to coat. Spread cashews on the prepared baking sheet.

Step 4

Bake in the preheated oven, stirring halfway through, until fragrant, about 40 minutes. Reduce oven temperature to 200 degrees F (93 degrees C). Continue baking, stirring every 20 minutes, until cashews look dry, 30 to 40 minutes.

Step 5

Transfer cashews to a container and let cool, shaking or stirring occasionally to prevent them from sticking together.
