How many people will a 3.5kg turkey crown feed just for dinner?

Here's why:

* Turkey crown portion size: A general rule of thumb is to allow 250-300g of cooked turkey per person.

* 3.5kg = 3500g: Dividing 3500g by 250g/person gives you 14 servings, and dividing by 300g/person gives you 11.6 servings.

* Account for bones: Turkey crowns typically have bones, which means you'll get less meat than a whole turkey.

Therefore, a 3.5kg turkey crown should be enough for 4-6 people, depending on their appetite and how much other food you're serving.
