Hi geeker and methi
Re 9a - I suppose this proves that it’s only well-known if you know it. All I can say is that I seem to have known about, and indeed enjoyed, this type of melon for years, if not decades. It’s a staple of most decent supermarkets and fruit stalls. It’s even part of Waitrose’s ‘Essential’ range (though that perhaps says more about Waitrose than about the fruit!)
Oddly though, I was wrong about the colour of the flesh. Late-night confusion with the cantaloupe which has a similar netted rind with orange flesh, whereas the galia’s flesh is in fact green. Mea culpa. And that’s enough about melons.
