I don't know what happened but all of a sudden the smell & flavor has changed & it smells very chemically. Almost like burnt plastic. I made an entire huge pot of all organic homemade soup (spent like $25 on all of the vegetables, maybe more) and had to throw it out because it smelled so bad. Amazon sent me another bag of this stuff but I wasted all that money & time on cooking. I got my 2nd bag this weekend, just did the same thing & ugh!!!! It smells off & chemically again!! Im so annoyed; all that money and time wasted. I have serious food allergies & have to cook in bulk so I can have leftovers to eat through out the week & this is a huge waste! There is something wrong with this new batch of nutritional yeast!! Be ware!! I was subscribed; ordering 2 bags a month and something has changed. Its so unfortunate!!
