Easy homemade dehydrated lime slices made right in your air fryer at 120°F. Perfect for cocktails, tea, lime powder, baking, and beautiful holiday decor. One ingredient, two hours, endless uses.
Wash and dry the limes. Rinse under cool water, scrub gently, and pat completely dry with a paper towel.
Slice evenly. Using a mandoline, slice each lime into 1/8-inch (3 mm) rounds. Discard the ends.
Blot the slices. Lay them on a paper towel and press another on top to soak up surface juice.
Arrange in the air fryer. Place slices in a single layer in the air fryer basket. Do not overlap. Work in batches if necessary.
Dehydrate. Set the air fryer to 120°F (50°C) using the dehydrate setting. Run for 2 hours. Check at the 2-hour mark — if slices still feel tacky, continue in 30-minute increments until fully dry.
Test for doneness. Slices should snap when bent and feel light and dry. The rind should crack easily.
Cool completely. Transfer to a wire rack and cool for 15–20 minutes. They will crisp up further as they cool.
Store. Place in an airtight glass jar with a food-safe silica packet. Keep in a cool, dark, dry place for up to 12 months.
