Fermented black bean in ready made pastes

Hi there! I am relatively new to Korean cooking and so I was delighted when a year ago my local supermarket (UK) started to stock ready-made gochujang and other products. However, the way I actually came to be interested in Korean cooking properly in the first place, was via some research into vitamin B12 done by Korean scientists. This is how I found out about the amazing health benefits of fermented black bean. So, I was devastated to realise that these supermarket-friendly brands don’t contain any real fermented-bean paste at all. The special health-benefit is gone, the flavour is not authentic, and worst of all, by making this cheap product, they are undercutting the asian food stores where we would otherwise be going to find good products, but then we see that they cost a bit more! I feel strongly about this but I can’t do anything. I wonder if Maangchi with her/your massive following of people who care about good Korean food might be able to raise awareness of this by showing which of the brands that are recommended for recipes actually contain the authentic fermented ingredients. It would raise awareness of WHY/how supermarkets are selling cheaper pastes, and give us all the reason we need to spend a little more on the good stuff :) Thanks for listening!
