Heat oven to 250 F. Arrange the pecans on a cookie sheet and toast, stirring occasionally, until fragrant, about 10 minutes. Meanwhile, in a large bowl, whisk the egg white and 1 teaspoon water until frothy. Stir in the pecans and sprinkle with the sugar, curry powder, and salt.
Mix well. Lightly coat the cookie sheet with vegetable cooking spray.
Spread the pecans in a single layer on the sheet.
Bake 1 hour or until the pecans are dry, stirring once or twice.
Store at room temperature in an air-tight container for up to 1 month or in the freezer for up to 4 months. Crisp the frozenpecans on a cookie sheet in a 250 F oven for 5 minutes.
