I find that a difficult one as I like both but possibly chicken as it is more versatile and is smaller and therefore, being alone, I can do more with it.
With turkey even though I like it, they are so much bigger that even at Christmas I end up throwing some out, and I think chicken is moister than turkey.
I do feel that a roast Turkey is a very impressive sight,but I personally find the meat dry,tough and tasteless no matter what I do t fix this!!! I do like the small rolled and filled Turkey breasts which you can get at Lenards. They are perfect when yyou live alone as well as seeming to cook with a far moister result.So
after all that,I have to admit to preferring Chicken.
You can cook them and freeze them in suitable sized portions, and you can make stock with the bones too. We quite often buy the drumsticks and make rice paper rolls with them too, and those are in a smaller sized packet.
Prefer chicken to turkey as the older children aren't too keen on the colour of the meat, more than the taste. We sometimes buy the fresh turkey legs to bake as it's just the two of us who eat it now.
If I'm going to eat some Turkey, I'll buy a marinated portion from my Butcher.
It's small, & cooked on Low, & Slow, it'll be just right!
With lashings of Mashed Spud, & gravy, of course!
