Asking because throughout my life (including when I was little) I’ve eaten cups full of raw pasta (the rice shaped little pasta) almost like it was a drink. I finished a 500g packet of wholewheat dry spaghetti just the other day. This is something I actually do so often I got told off by my dentist last year because it’s wearing my teeth down.
Outside the US, 3L is pretty common. I’ve RARELY seen them in the US and mostly at import stores.
