I also was overtaken by a desire for lemon squares. Dunno, I've never made lemon squares, but for some reason it sounded good. And they are also yummy, although next time I'll put more lemon juice in there. They are surprisingly easy, and I got my recipe from here. I do like both the lemon stuff and the crust together, but I could also just eat the crust, which is made from flour, powdered sugar and butter (wow).
