I'm about to put the Turkey in the oven (roast) and it says the temp and time but should I put some liquid in the bottom??? Some water or something??

Help! It needs to go in now! It's been years since I cooked a roast! So how long to roast pots take if I par boil them first??

So I boil them for how long?? And then when do I add them to the tray with the turkey on?

TIA!!
