Tarte Tatin and 1917; whereas Maxim's was purchased by the Vaudable family in 1932. Originally, the tarte Tatin was made with two regional apple varieties: Reine des Reinettes (Queen of the Pippins), and Calville. Over the years, other varieties have tended to displace them, including Golden Delicious, Granny Smith, Fuji and Gala. When choosing apples for a tarte Tatin, it is important to pick some that will hold their shape while cooking, and not melt into apple sauce. In North America, Golden Delicious, Granny Smith, or Jonathan are excellent choices . Tarte Tatin can also be made with pears, quinces, peaches, pineapple,
Morphism of algebraic varieties that the category of affine varieties can be identified with a full subcategory of affine schemes over "k". Since morphisms of varieties are obtained by gluing morphisms of affine varieties in the same way morphisms of schemes are obtained by gluing morphisms of affine schemes, it follows that the category of varieties is a full subcategory of the category of schemes over "k". For more details, see . A morphism between varieties is continuous with respect to Zariski topologies on the source and the target. The image of a morphism of varieties need not be open nor closed (for example,
