So, in the UK we have a supermarket called Sainsbury’s. They’re one of the few supermarkets in the UK that regularly stock ‘exotic’ mushrooms. To the UK consumer anything beyond a white mushroom is considered exotic so I think they’re pushing that terminology a bit there. They also happen to be in pretty poor condition having been crammed into the packaging, bruised and bent around each other, it gives a really bad first impression to people who want to try new mushrooms.
I’d just set my lab up in my shed and needed to test run my new-ish HEPA filter and all my kit, I’d knocked up some agar from Malt Extract and Agar Powder and shot down to Sainsbury’s.
The bags were sterilised in my ‘Bubba Barrel’ you can checkout my video by clicking Here or on my YouTube channel that discusses the design behind that. I have done a full write-up on how to build one, but I didn’t take pictures, so I need to build another one and take photos.
I then transferred the agar to my bags in front of my HEPA and heat sealed 2 and cable-tie sealed the third. I did this because I’m not having much luck with my heat sealer right now, the heat seems to be unevenly distributed along the entire length, meaning it ‘cuts’ half the bag and seals the other half which is irritating.
