As printed, this recipe was not lemony enough. Using other's suggestions, I tried it again using the juice of 5 lemons (a little over 2/3 cup) and the zest of two lemons. I also added 1/3 c. flour to compensate for the extra liquid. I also had to increase the bake time to about 24 minutes. These turned out GREAT with the extra lemon (and, of course, powdered sugar on top). I also added a dash of salt to the crust and thought it was divine. These weren't anything flashy or out of the ordinary...just exactly what lemon bars should taste like.
