It's been just over 2 weeks.  I tried the mustard (see 3/7 entry)  after about 4 days and it still had a vinegary taste to it.  That is all gone now.  What flavors are there?  Heat!  Is heat a flavor?  I'm not really detecting any of the other ingredients or spices.  Maybe I added too little? 

Then again, it's not the kind of heat that just mustard powder and water produces.  I'm going to give it a small dose of honey and report back in a week or two on the change if any.
