Sugared Zucchini Blossoms

Preheat oven to 275 degrees. Halve blossoms lengthwise; remove stamens. Very gently toss with oil and sugar. Place on a rimmed baking sheet lined with a silicone baking mat or parchment; bake 10 minutes. Using an offset spatula, gently flip blossoms; bake 5 minutes more, then flip again. Repeat, checking frequently to avoid burning, until dry to the touch, about 20 minutes more. Transfer to a wire rack; let cool completely. Blossoms can be stored in an airtight container in a cool, dry place up to 3 days. Recrisp in a 275-degree oven before using.
