There is nothing better or easier than a quiche for a Sunday brunch. I love that I carry them in two sizes. Sometimes you just want to make a smaller portion, so the 8" is perfect. I not only use these for quiches, I use them for tarts and my favorite, almond cake. These dishes cook things beautifully and the clean up is great.
