How long do you cook 7kg of turkey crown for?

I can't give you an exact cooking time for a 7kg turkey crown. Here's why:

* Oven temperatures vary: Different ovens heat differently, even if they're set to the same temperature.

* Turkey crown size and shape: A 7kg crown could be quite different in thickness and shape, affecting cooking time.

* Stuffing: If your crown is stuffed, it will take longer to cook than an unstuffed one.

Here's how to determine the cooking time:

1. Use a meat thermometer: This is the most reliable way to ensure your turkey crown is cooked through. A meat thermometer inserted into the thickest part of the crown should register 165°F (74°C) for safe consumption.

2. Follow your recipe: The recipe you're using will likely provide a general cooking time based on the size of the crown. Adjust this time as needed based on your oven and the internal temperature.

3. Check frequently: Check the turkey crown's internal temperature frequently during the last hour of cooking to ensure it's cooked to the right temperature.

4. Rest: Once the turkey crown reaches the correct temperature, let it rest for 15-20 minutes before carving to allow the juices to redistribute.

General guidelines for cooking turkey crown:

* Allow about 20 minutes per 500g (1 lb) of weight: This is just an estimate, and you'll need to adjust based on factors like stuffing and your oven.

* Start with a higher temperature (around 180°C/350°F) for the first hour or two, then reduce to 160°C/325°F for the rest of the cooking time.

* Always check the internal temperature with a meat thermometer to ensure it's safe to eat.

Remember, it's always better to err on the side of caution and check the internal temperature frequently to ensure your turkey crown is cooked perfectly.
