I decided to pre-cook it today and freeze.
Never cooked turkey before - my first Christmas as host.
Bought turkey crown and a leg. Followed this recipe www.goodhousekeeping.co.uk/food/recipes/glazed-turkey-crown which says to do on Gas Mark 5.
Worked out timings and it should've needed an hour and 45 mins (it's only about 4lb - butcher weighed it for me). Butcher said take leg out after about 45 ish mins as it won't take long.
It went in at 15.05 and I took it out at 15.45/50 to have a look at the leg and it was still almost raw. :( Not sizzling or anything either when I went to baste both pieces about 10 mins ago.
Done a bit more digging around online for temps for turkey. Found lots of places saying to stick it in very hot oven (Gas Mark 7) first. eg this site britishfood.about.com/od/christmasrecipes/a/roastguide.htm
Have I put it in a too-cool oven? I'm pregnant so stressing bit more than usual about potential salmonella! But I don't want to give my family food poisening either.
