How to make dried rhubarb chips, a simple rhubarb garnish for desserts, sorbets, cheesecakes and even savoury dishes. Inspired by the elegant fruit decorations often seen in Paris restaurants.
Wash and trim off both ends of the rhubarb. Using a mandoline cutter, slice the rhubarb as thin as you can, leaving on the rhubarb skin (please be careful and use the security attachment)
Bring the water and sugar to boil in a saucepan.
Transfer the rhubarb to a long shallow dish that will hold the rhubarb slices, depending on the length you wish to create for each chip. Pour over the hot syrup, ensuring that all the slices are coated. Cover the dish with cling film (plastic wrap) and leave to cool for about 15 minutes.
Preheat the oven to the lowest setting you can, no more than 90°C/200°F (70°C fan).
Dry the rhubarb slices on kitchen paper and place them apart on non-stick trays (slices touching will end up sticking together).
Dry in the oven for up to 2 hours. Keep an eye on them after an hour, to ensure they're not darkening. If they're small, they will require less time to dry.
Notes
Rhubarb chips work best if using larger sticks of rhubarb.Storage: Store in an airtight container in a cool, dry place for up to 2 months. If the chips soften slightly, return them briefly to a low oven to crisp up again.Dehydrator: I don't own a dehydrator so haven't personally tested this method. However, readers have asked about using one and it should work well on a low setting (around 55-60°C/130-140°F). If you've tried making these rhubarb ribbons in a dehydrator, I'd love to hear how long they took and what worked best for you in the comments below.
