Lemon bars made with gelatin give you a clean, precise slice when all is said and done. They're great for presentation. Lemon bars without gelatin are more gooey, less showy, and meant for Sunday afternoons sitting on the porch catching up with a close friend. They are completely lacking in pretension-- they may not totally hold their shape while you're trying to plate them up, so you might as well eat them right out of the pan.
