I made this last week for me and hubby and it was a big hit! Only change I made was I used dried thyme, but half the amount called for, since dried herbs are stronger than fresh. I've never really had vermouth before, so I wasn't sure how I'd like the sauce, but it was wonderful and earthy--excellent compliment with the mushrooms and thyme! Served with the creamed spinach recipe from this site (also amazing!!) and mashed potatoes. We will be making this again!!
