To preserve rambutan

I keep letting the rambutan rot away without really have the chance to preserve it. To preserve 1kg of fresh rambutan, shelled the fruit we don't want the hairy fruit skin. Put it in a container, it can be either a plastic container or glass bottle container. Add and dissolve 3 tablespoons of salt into a cup of water. Pour the salty liquid into the fruit. Let it stay overnight in the fridge for a better taste. You can keep it in the fridge for up to a week.
