I use bay leaves frequently - mainly stew / chili type dishes.
tomorrow is split green pea soup chunked up with corned beef - and there will be bay leaves used....
it's a subtle flavor - but DW easily picks up on it . . ."did you put bay leaves in this?"
over doing it can produce unpleasant results.
a little works, a lot not.
If you use fresh bay leaves it really does make a difference.
