Here's Emiril's recipe for Julia's Tart along with a video of Emeril and Julia cooking it.
Julia calls for Golden Delicious apples which are very abundant this year on our tree. You will also see other recipes call for Granny Smith, MacIntosh, and Gala mentioned as well as any good baking apple. You just don't want an apple that will turn to mush.
What were the apple varieties used in France?
Wikipedia says Reine des Reinettes and Calville were used. We have grafted these two varieties on our apple tree, so next year, maybe we will get to use them.
