I used to use Ebay a lot, and thought about it without really checking, thanks!
Now, the problem might be, is it actually vegan? Do I have any way to check if it is? I got the following information while searching for the culture:
- https://www.amazon.com/gp/product/B06VSHBBQZ : this is the one used by the fullofplants recipe, the one at the top of this subreddit, and according to the vendor (in the questions) is not vegan because it is propagated in lactose
- https://www.thecheesemaker.com/products/Penicillium-Roqueforti.html : according to them, any strain but the PRB6 are not vegan, or at least the ones they sell are not
- https://www.amazon.com/Queso-Culture-roqueforti-molde-hacer/dp/B079TMT6YB : I think this is the same brand as the link you gave me, and according to the vendor it is not vegan
I think it will be good to expand the post.
