Blend all crust ingredients (except for egg yolks) until they are the texture of coarse meal. (You can use a fork, a pastry blender or a food processor). Add the 2 egg yolks and mix well to blend. **Set aside 1/4 of this mixture and save for later**. Using the remaining 3/4 of the crumbs, pat them down over the bottom and up the sides of a tart pan with removable bottom disk (this is what I use) or a pie pan. Make sure crust is firmly pressed down into the pan and the sides to form a solid crust.
