Zenn,
yeah, everbloom is the brand. It's a local brand (can be found in most supermarkets) so I feel better about it somehow. LOL. Been to the farm before when I was younger.
Zenn/Char,
I washed whole mushroom first, then sliced and diced the mushroom, soaked the pieces in hot water, before putting it in to cook with her porridge. Thought it'll be 'cleaner' if I soaked the pieces in hot water first, but then actually I realise that in the process also lose quite a bit of nutrients?? So maybe just wash clean will do?
