Fatty question, potatoes?

[wnc goater]

A question for the fatty experts. If potatoes are diced small and used as a fatty stuffing, will they get done? I'm wondering if 3+ hours to 165-175 IT will leave the potatoes not cooked to tender stage.
Going to try my first fatty tomorrow with potatoes diced small, provolone, onions, and mushrooms. Now I'm second guessing this plan.

Were it I, I'd be afraid to put raw potatoes in my fatty.  I think I'd cook them some before.

I sort of came to the same conclusion and ended up cutting into 1/4" cubes and sauteing in olive oil.
Thanks for the reply!
