  • Dry them for 3-3.5 hours. The exact time depends on the thickness of the flesh. Start checking regularly after 3 hours. Remove longan from the oven once it is dry and dark brown (or even almost black) in color.

Notes

The quantity of longan fruits is just a suggestion. You can dry as much as you want. It can take about an hour to remove shell and seed for 2 pounds (900 grams) of longan.
From 2 pounds of longan, I get about 1 pound (450 grams) of the flesh only. After dehydrating, I end up with about 3.5 oz (100 grams) of dried longan, about a cup.
You will need a small paring knife with a sharp tip to remove the shell and seed of the fruit. It is best to watch the video in the post to see how to do this.
I use a convection oven and dehydrate the longan with the fan on. If you have a conventional oven, you may need to add more cooking time and rotate the baking tray once in a while. Or try increasing the oven temperature slightly by 10-20°F.
Usually the darker the color, the dryer the fruit and the longer you can store them.
