1. Having dulce de leche for breakfast and drinking Coke at every meal
Argentinians have a sweet tooth and love their Coca Cola, dulce de leche, ice cream, dulce de membrillo, and medialunas. In Buenos Aires I learned that biting into a tostado with a thick spread of buttery, fudgey dulce de leche the first thing in the morning is completely normal and you’re only judged if you don’t start your morning with a massive sugar intake. It’s also completely fine to drink Coca Cola with every meal and use it as your staple drink mixer (I might add that it never ends with just one Fernet with Coke). I once tried to introduce the Fernet Orange to at least add some Vitamin C to my alcohol intake, but as horrified locals stared me down, I decided to stick with the national drink.
