As someone who lives in Buenos Aires, Argentina... I felt like I had to chime in. I'm a HUGE Dulce De Leche fan... gimme a container of it and a spoon and you'll see it disappear in 10 minutes. I have tried just about every brand they sell here, and believe me, none comes closer to the Conaprole brand dulce de leche from Uruguay. Unfortunately they don't sell it here, so every time I go to Uruguay I bring back 4-5 jars of it. I've seen it sold on eBay a few times, and also this online store seems to sell it: http://www.amigofoods.com/codudele440g.html If you ever have the chance to get some of it, by all means do... it's amazing. As for the sandwich cookies, the correct name is Alfajores, and there's tons of varieties. Probably the most famous Argentinian brand of Alfajores is Havanna ( http://www.havanna.com.ar/ ). They are yummy. Here in Buenos Aires you have about 20 different options of Alfajores when you go to the supermarket. If you wanna take a look at what's available, go here: http://www.cotodigital.com.ar Click on "Saltear Introduccion". Then click on "Ingresar Como Invitado". Then, on the left pane, open "Panaderia y Golosinas" > "Golosinas" > "Alfajores". Another type of alfajores is "Alfajores De Maicena" (cornstarch alfajores). They are crumbly and delicious. If you want a good recipe for them, let me know and I'll post it here. Cheers, Federico
