The standard fare poutine around here is made with curd-like mozzerella I think, its kinda mushy like the fries themselves, its just called “poutine”. I’ve never had poutine with cheese so squeaky like I had that one time in Quebec, it was firm, chewy, and loud. Probably about 15 years ago now. Never had anything like it since.

Squeaky cheese

This style of cheese originated in the province of Québec in the 1960’s. At the time, local dairy farms had surplus milk, and they needed to use it for something. Cheese-making, it turned out, was the ideal solution.

All cheese is made from curdled milk, and Squeaky Cheese is no different. The main difference between cheese curds and the traditional blocks of cheddar you see in the grocery store is age and whey content.

It’s been in Quebec, where it’s made with squeaky cheese. I had some from a roadside poutine stand there one time. The first time I ever had poutine was in Timmins, Ontario, about 40 years ago. Blew my mind it was so good.
