One of the most satisfying treats I came across in Buenos Aires was the facturas - little pastries sometimes filled with delicious caramel (dulce de leche) which I was introduced to by a Chilean girl who lived with us some years back but had never found in such delicious treats before. My friend Saboo loves these pastries, particularly the media lunas (like croissants - see picture) as much as I do and she has discovered that you can indeed get them in Sydney and Melbourne at...
Confiteria Macel, shop 3, 63A Brennan Street, Smithfield, NSW
El Molino, 3/105 Tangerine Street, Fairfield East, NSW
and in Melbourne at
Cafe Tango, 107 Hoddle Street, Richmond.
