Frutigran is an Argentinian cookie made by Granix. The one I like best is in the yellow package (con Salvada). These things are totally addictive. I brought only one package back to NY from Buenos Aires, and then discovered, to my horror, that I couldn't find any here.
If you know an Argentine grocery that sells this product, or will ship it in the US, please let me know. So far, I have discovered that I can order it on line from Argentina (from Staples no less), but then I have to pay ridiculous shipping. Help!!
