Melting moment is a name that is applied to many different, yet similar, types of cookies. Some are crunchy, while others tend toward a softer feel. The most common ingredient is cornstarch/cornflour, but they occasionally contain finely ground nuts (this makes them Mexican Wedding Cookies, but I've still seen them called melting moments). The one thing that they all have in common is the property that gives them their name: they are so tender that they melt into your mouth. JenJen, at Milk and Cookies, posted these Melting Moments, which she made with high quality butter and cornflour. They're lightly sweetened, dusted with powdered sugar and, of course, melt into your mouth. I love the jar that she presented them in, too. Not only is it a nice visual touch, but it looks like the cookies are ready to ship out to anyone who wants to taste them, unless you want to try making your own.
