Romeritos is a Mexican dish I learned a bit about tonight in my Spanish class. Basico 2 is a 6 week intensive at UNAM ESECA that seems to include some grammar, a lot of words and occasional culinary lessons on celebratory foods. There's also valuable tidbits like Mexican for Avocado is "aguacate", but in Chile and Argentina at least, you're better off asking for "palta."
Jan and I learned about what palta tastes like when it's fresh and didn't travel 10,000 km before being consumed when we were in Chile and Argentina. OMG, they are amazing and they are an amazing condiment; beats ketchup on any burger!
