ketchup

Every wonder why it says tomato ketchup on a bottle of Heinz? Which, to those of you who love language, implies that there are other kinds of ketchup?

That's because there is!

Ketchup is a tangy bottled sauce of sorts. Tomato being the most popular. But there is mushroom ketchup, walnut ketchup, strawberry ketchup... The list goes on.

How is this something I didn't know until last night?
