Midtown Lunch reports that Kolache Mama (perhaps she’s in the same PTA group as Empanada Mama?) will open the first of two locations in Midtown East this September, at the Roosevelt Hotel. Cursory research indicates that kolache are the Czech Republic’s contribution to the world’s stuffed carbohydrate canon: They’re pastries filled with a variety of savory and sweet ingredients and, as ML notes, are similar in appearance to everything from a bagel with spinach on top to a pig in a blanket. They’re well-known — and well-loved — in states with sizable Czech populations; Texas in particular is known for its kolache. The Kolache Mama website somewhat worrisomely describes its product as “fast food for foodies”; whether or not New Yorkers will agree remains to be seen, but it’s likely that Kolache Mama’s “Tuscan Chicken” and “Philly Beef” pastries don’t have too much in common with what mama really used to make.
