Küchen de Quesillo
Chilean Cheesecake

In Chile, pies and tarts are called küchen, simply because the bakeries which originally  sold these items were German, and are traditional in the German households. We could call this a cheesecake, but cheesecake is technically neither a cake nor a pie, but a custard.

This recipe uses Chilean quesillo, but you can substitute Schmierkäse(what the Germans use for this küchen), or Neufchâtel, or a Mexican fresh cheese such as queso fresco or panela, or, if you live in Tulsa, 1½ cups of ricotta and ½ cup of heavy cream.

In the U.S., cheesecake is made with cream cheese, which is slightly more ripened and thus tangier than those listed above. Cream cheese was invented by accident in New York in 1880, when a cheesemaker tried to create a duplicate of Neufchâtel.

This pastry is traditionally served at tea-time, German-style with fresh raspberries or blackberries.
