Anyone growing Cucamelons?

I've just been given some cucamelons and they seem a great additive for salads..

Question - the seeds around are £2 a pack + postage.. Eeeeks!! so does anyone know if I can save seed from these that I have been given?

If they're the same as the ones on the Realseeds site (and I think that they are), then I should think the seed can be saved.

I'm guessing it is the same as when you want to collect cucumber or melon seeds: an extremely ripe fruit first, followed by rinsing off the gel, and then drying on kitchen paper.

Remember I am guessing  :blink:
