The block to hang up outside for air drying is called 메주 (meju) which is form before made into 된장 (dwenjang). There is more process involved to make it into dwenjang. Actually from that meju we make daenjang and soy sauce.

Don't forget the larva which is apparently a sign of a good 메주. I wonder how many people can still put up with the smell of making it at home.

I really need to learn to make 된장찌개 at home. This thread reminded me how tasty it is.
