All timings are approximate and adjustments may be required based upon your oven.
Preparation, Cover breast flesh in soft seasoned butter and wrap in bacon, slow grown birds often require less cooking so always check any farmers cooking instructions.
Calculate timings. Always preheat oven, for fan ovens reduce temp by 10-20c Allow 10 mins per 450g/1lb up to 4kg + 70 mins. Allow 10 mins per 450g1lb for weights over 4kg + 90 mins. Cook at 190c/375f/Gas mark 5, finishing, Remove from oven when internal temperature reaches 70c and then rest for at least 30mins or until temperature reaches 75c. Do not cover otherwise the heat will soften the crispy skin, don’t worry it will stay warm.
