This particular tart is very popular in Argentina. You can see it in every bakery shops or cafes. This is a simple tart feacturing a filing of ruby red dulce de membrillo (mem-bree-yoh) or quince paste. Sometime this tart can be found with dulce de leceh, sweet potato (dulce de batata), guava paste (dulce de guayaba) fillings too but the authentic one is using dulce de membrillo. It is usually eaten with a cup of coffee or mate .
Like most of Argentine recipes, this tart owes its existence to the Italian immigrants who made Argentina their home during the 19th and early 20th centuries. Carlos being an Italian grew up eating this tart and I even bought a few Spanish cookbooks( I can’t seems to find any English cook book there) so I can make some of the Argentinean desserts and dishes for him.
