How long to bake 15 tatties in the oven for?

As above? How long will it take for 15 of them to cook?

The same as it takes one of them to cook.

No, it'll probably take longer because your oven will fill with steam. I would work on 20 minutes longer. If they are done earlier, you can always switch the oven off and just keep them warm in a T towel.

OK. I was hoping for roughly the usual time of 1 but I will go with about 1.5 hours beforehand. Thanks.
