Hi guys,I'm new here. My husband and I own a small european style bakery.We sell a lot of kolaches.We make an yeasted dough, roll it very thin, fill it with walnut,poppy seed,cottage cheese,dried apricot,cocoa filling,raisins,turkish lochum or just plain.In all the fillings we add the egg whites beaten with sugar ,that's the secret to cling with the dough.Sometimes I make individual danish and I freeze them,and in the morning I defrost'em and pop in the oven,but doesn't work as nice as the fresh ones.We keep them in the plastic bags and they have a two weeks shelf life.They have a better taste after 2-3 days.Our russian,serbian.hungarian,romanian(we are from Romania),american and mexican customers are very happy with the kolachy.I love to post some pictures but I don't know how!
