i'm going to try the Babka again for a potluck. and luckily enough i got a direct response to the lack of flaky-ness. by direct i mean direct from peter reinhart himself! so here we go with peter's suggestion:
before I forget, you are right about the babka and here's the reason why
: there was a typo and they forgot to add to the ingredient list for the
dough 1 oz. (2 tablespoons) of vegetable oil, any kind,
(this is in addition to the butter).
i'll try the recipe again with the vegetable oil and we'll see how it goes.
Thanks Peter!
