I found gochujang at Costco! Never heard of the company brand name 'being blue' but the price was much lower than asian market...$9.97. We bought one to try with lettuce wraps and it tasted fresh and good gochujang.
We didn't try cooking with it yet, but so far we like the taste and the price. Hopefully they don't take it out from inventory. We will definitely go back for more!
Here's the back label for you to see.
