Two ready-to-sink hot chocolate (submarino) kits. Dunk a chunk of artisanal chocolate into some hot milk and enjoy your own submarino at home. Argentineans don't mess around when it comes to hot chocolate - a glass mug of hot milk and a bar of dark chocolate is how they roll. The chocolate is the submarine, and you sink it into the piping hot milk - Titanic style. Stir it as you giggle maniacally. Drink up. If all goes well, a delightful treat of melted chocolate sludge waits for you at the bottom of the milk sea.
