Ugh! I wan't this now! Seattle has a large Polish population and every year there is a Polish festival celebrating the culture, mainly through food. If I had known that lemon poppy seed cake would be involved, I would have tried a little harder to weasel my way into the festival.
Smitten Kitchen, one of my favorite baking sites, posts a wonderful rendition of lemon poppy seed cake inspired by her mother, who is Polish. You can find the recipe here and glance at Smitten Kitchen's beautiful photos below.
