Polish apple cake - placek z jablka (plaht-SEK zhe YAH-boo-kah) - and Polish cheesecake - sernik (SEHR-nik) - are two of the most frequently seen desserts at Polish tables. There are hundreds of recipes for both. This is how my family likes apple cake. The Polish version of apple pie is known as szarlotka. But this is truly a cake -- placek z jablka literally means "flat cake with apples." Try plums, peaches or nectarines in this recipe to good effect.
