OMG....this is WORTH the investment. Case closed. I actually start with the bags in cold purified water, bring to a boil with a lid on, drop the heat to med ium & then boil 10 minutes. Then off the burner & sit until cooler. What you arrive at is a gorgeous broth that achieves a CLEAN FRESH UMAMI BROTH.
I will say for newbies to cooking Korean cuisine. Despite the obvious fishy scent the broth is not...AND THAT COMES FROM THE QUALITY OF THE INGREDIENTS.
GORGEOUS

These broth packs are fantastic! They're easy to use and they make a very nice base broth to work recipes from.

These broths make cooking so much easier and convenient!

I was very excited to try this because there are so many recipes that use this as a broth and me and my husband don't usually eat seafood so I was afraid to buy the anchovies by themselves. This pack was so easy to use that I didn't have to mess with the fish at all and it turned out delicious.

I found out about this product because @LauraIz featured it on her beef radish soup recipe, and I couldn't find it in our local Korean supermarkets here in Canada. I was so glad to find these on Gochujar and it shipped super fast, especially because it usually takes longer to arrive in Canada. Daniel was great at answering my questions about it as well!
