Classic Upsidedown Apple Tart

This is the most famous apple tart of France, and once you have mastered its special technique, you will probably never want to make any other. (For the story of the sisters Tatîn and the accident that led to their invention–menu with wines.) The tart will, of course, have a different character with different kinds of apples. Try it especially with Greening, Rome Beauty, Northern Spy, Winesap or York Imperial. . . .
