Ok here's some follow-up on some stuff we discussed today:
1) Wild edible things to forage in the suburbs:
Check out this group from Melbourne: http://www.eatthatweed.com/
I was given the handbook on the website as a gift from my parents which I can being along to a future meetup if anyone is interested. In Perth I have found: Sow thistle, plaintain, dock, sorrel, blackberry nightshade, wild brassica, wild lettuce, blackberries (only occasionally), fennel (although all the ones I have seen look very tough), cleavers, oxalis ('soursob'- my backyard is full of it!), nasturtium, mallow, prickly pear. I haven't seen many true dandelions over here- there is a similar species everywhere called 'cat's-ears' and although it is edible it is too bitter for me to want to eat. I haven't really encountered nettles, Warrigal greens, wild celery, sheep's-sorrel, wild onion or wild roses much in Perth. Pity, I really like nettle gnocci! I do intend to ask my neighbours about their olives which are so ripe they're falling from the tree, and their peppercorns too.
I tend to buy something with a recent roast date from one of the local coffee brands (Rubra and 5 Senses are based in Perth)- whatever I can see. If the roast date isn't on there, look at the 'best before' sticker and subtract a year from it. However another option is pick your favourite non-franchise cafe- if you like their coffee and you can see they grind their own beans, ask them to sell you a bag. Many are happy to oblige.
@Happier, I hope you do feel better.
