rubbery potatoes

i've tried scalloped potatoes using a chicken stock (i can't use cream base- kosher kithcen)- they cook very strangely- either too done or underdone, with a tough texture- i've tried blanching, part way - nothing sems to help- any advice or recipes?

by the way, i have great results simply roasting fngerlings...

Try roasting finglerings in salt....
Cover your Potatoes Anna with foil for half the cooking time then open it rest see if that works for you....do you not have dairy and meat....or just meat and parve? I've been using 3 sets of cookware for 2 years, for a kosher student. It really is not that difficult.

Could you outline your procedures? I can't quite figure out why they would be rubbery.

Yeah let us in on the method! If they are tough, i would think that they are under cooked. But rubbery? Hmmmm.

Uri, could it be the variety of potato you're using? I'm not sure which are best for this dish, but maybe that's it.
