This looks like an excellent dinner that I would be happy to eat. That being said, there is acres of room for improvement, some of the scores being bandied about on here are laughable, especially Tighty's 9/10. he must be a very inexperienced eater.
Now for some realistic marking.
First, the good.
Meat looks ok, reasonable portion size ect. + .5
Roasties look decent but nothing special.
Carrots look really good. +1
Now the bad.
Yorkies- Dry and brittle looking. one bite and they shatter into sawdust. even if you add gravy it wont help. - 1.5
Meat overdone but it's difficult to tell because of the overly dark gravy. (Too much browning imo) - .5
Too little gravy, no gravy boat for topping up. - 1
No peas. (FWIW Sunday dinner peas should be the kind that you soak overnight with a soda tablet, but no peas at all is unforgivable) - 1
No cabbage. (dark green cabbage with bacon fat could be worth a whole extra point) - .5
No cauliflower (Cauliflower with cheese could be worth a whole nother extra point) - .5
No mashed potato. - 1
No cranberry or apple sauce. -.5
No bonus veg like sprouts or roast parsnips - .5
Small, slightly boring plate. - .5
Small overall portion size. - 1
No beverage of any description. - .5.
No cutlery. - .5
Assuming a starting point of 10 that leaves us with a grand total of 2.5/10.
I sincerely hope the standard improves from here on in.
