Hello mushroom nerds! I need some help identifying my problem here (Or if this is a problem). I have been experimenting lately with intense pasteurization of my bulking substrate by pressure cooking the entire mixture (choir, verm, and some more wild bird seed). Obviously this leads to some concerns with the moisture content. You can see in the pictures that this jelly like substance has covered my whole cake. It has very strong colonization otherwise and the smell is fine. I was surprised to see this when i trimmed my plastic back before putting my tub under lights. I am kinda wondering if by cooking my substrate i didn't brew a cocktail of nutrient broth which then colonized with mycelia like an agar or something. What do you guys think? Thanks for the input fellow nerds!

Are you rinsing the birdseed before adding it? Grains do give off a broth that solidifies like agar.
This article has pictures of it:

When you go to pour your grains into a strainer to drain off the water, be sure to have something to catch the water!
Here is that liquid after some time of settling. The top liquid is poured off into a container of its own...
... and the settled part combined while leaving behind any stray grains.
The right container of opaque liquid essentially amounts to AGAR!
The left container of settled grain matter in liquid can be settled further and more grainwater pulled off the top:
... leaving behind a thick almost syrup solution of grain starches and nutrients. With ~1/3 the normal proportion agar-agar powder and a little help from another trick this amounts to more substrate, but that's something else altogether!
Both can be frozen for later use.
