How long does it take to cook a 4.6 kg turkey crown?

I cannot give you an exact cooking time for a 4.6 kg turkey crown. Here's why:

* Oven variations: Ovens can have different heat distributions, even if they are set to the same temperature.

* Turkey crown size and thickness: A thicker crown will take longer to cook than a thinner one.

* Bone-in or boneless: A bone-in crown will take longer to cook than a boneless one.

* Stuffing: If you are stuffing the crown, it will take longer to cook.

To determine the cooking time, you should:

1. Refer to the recipe: The recipe you are using should provide an estimated cooking time for a turkey crown of a similar size.

2. Use a meat thermometer: The best way to ensure your turkey crown is cooked through is to use a meat thermometer. The internal temperature should reach 165°F (74°C) for safe consumption.

General guideline: A 4.6 kg turkey crown might take around 2-3 hours to cook. However, always check the recipe and use a meat thermometer to ensure it is cooked properly.
