Cheese curds on poutine
Curds were a component of milk.
The Canadian dish poutine consisted of cheese curds and gravy on French fries. (SNW: "Tomorrow and Tomorrow and Tomorrow")
The manufacture of cheese involved separating curds and whey from milk, a process which would take days to complete. In 2374, Neelix cited this fact as part of the reason why it would take a while to make pizza from scratch, upon which Tom Paris conceded that the Talaxian could replicate the cheese he needed.
