Two whole turkeys would require more cooking time. The heat energy in the oven would be absorbed more to the point that the turkeys wouldn't be cooked fully at the end of the time. The best result would be to double the time on the oven, while checking periodically with a food thermometer to see when they are ready.
No, although you do need to make the oven hotter acording to the sixe of the piece of chicken. Reminds me of the Blonde who wanted to double her recipe for Chocolate Chip cookies but decided she could not do it. She realized her oven would not go to 800 degrees.
See the link below for cooking times and temps for turkeys.
No, the cooking time remains the same.
No, cooking time is only affect by how big or small your baking pan is. If it is larger, use the same cooking time to accommodate the larger portion.
about 4 hours at 350....check after 3 1/2 some ovens are hotter than others.
yes
If porcupine meatballs are the same as most other meatballs, i.e. cooked in the oven in balls the same size, then no thereis no need to double the cooking time.
Absolutely. Depending on the recipe, there may be other small adjustments (like cooking time), but for the most part, just double it all.
bush turkeys can only fly for a limited amount of time
Most home ovens are not large enough to bake two turkeys at one time.
just with the same food
A double cast iron grill press can be used to press food to a grill while cooking. This action can cause food to be cooked more thoroughly and decrease cooking time.
