This was awesome!!!! One of the best turkey dishes I have ever tasted. My husband made a point to let me know we should have it again!! I didn't have tarragon, so I used a little garlic powder for an extra spice. I also used a skinless turkey breast.
I made this in the oven, well covered, at as low a temperature as my primitive oven would bake. I also scaled the recipe by one third, for only 1 pound of turkey breast. I kept to the recipe's proportions for most things, but did increase the mushrooms considerably. I also used dry vermouth, rather than white wine. I baked the turkey breast for 3 hours, which, in retrospect, may have been a little too long. I then attempted to slice the meat, but ended up shredding it. I next cooked it in the mushroom sauce, adjusting the salt and pepper. It is quite good. My only problem is more a matter of personal taste than anything. I did use the tarragon, but am not so sure if I think it goes well with the turkey or not. Thank you for posting this recipe. I enjoyed trying it.
