If you don’t have a dehydrator
- Spread the berries on a tray not far from a heat source (fireplace, wood stove or warm radiator).
- Set a low-speed fan to send warm air around the berries.
- Check on them every couple hours to turn them over.

- Let dry for around two-three days. Remember to empty the water tank when full.
- Don’t spill them or you’ll stain the carpet or woodwork!
In the oven
Usually this isn’t the most cost-effective solution, but it works.
- Open the door to the oven, and set it on low (130°F or 55°C).
- Spread the berries on a tray, so that they’re touching but only the occasional berry sits up over other berries.
- If your oven has a fan function that circulates air, turn it on.
- With the door opened up a crack, let the heat do its thing and dry the berries out. Moist air needs to be let out of the oven, hence the open door.
- Open the door to shuffle the berries around every couple hours.
- This can take up to 8 hours. Either start early, or interrupt it overnight so you don’t create a fire hazard.
