As a non American I only know how to hide them.

Are they just salted biscuits?

I’m not an American either but yes, saltines are salty biscuits.

Now just wait a damn minute here, is everything just called a biscuit outside of the US? Cookies are biscuits and now crackers are also biscuits? How do y’all distinguish things‽ “I’d like a biscuit” must be this dangerous game of roulette where you might get a delicious chocolate chip cookie or you might get a dry ass saltines or little teeny oyster crackers or God knows what else.

Y’all need new words for shit

No. American is not correct by default.

Crackers are biscuits, cookies are also biscuits. A Toyota Camry is a car, a Dodge neon is also a car, its not that hard. If specificity is important you specify.
