Are seeds in melons and other fruits good to eat?
In Northern India, we eat Musk Melon and Water Melon seeds. In fact they are used like nuts. We make sweet dish too.
The de-kernelling process is done by hand at home, which is quite lengthy.

We deseed melon. Put the seeds to dry for approximatively 2 days; with fingers or tweezers, break the kernel and get the yummy seed. Of course, it can be stored for months, if dried properly, and for years, if kept in freezer.
