I have lived in Canada for nearly 40 years. When someone first told me about poutine (French fries, melted cheese curds, and brown gravy), I couldn't imagine people would crave such a dish.
Craig Newmark has loads of information about poutine here.
Here is the introduction to the article in Wikipedia,
Poutine (pronunciation in IPA as heard in Quebec French [puʦɪn] — listen to it in .wav format) is a dish consisting of French fries topped with fresh cheese curds and covered with hot gravy (usually brown gravy) and sometimes other additional ingredients. The curds' freshness is important as it makes them soft in the warm fries, without completely melting. It is a quintessential Canadian comfort food, especially but not exclusively among Québécois.The Wikipedia article also mentions the role of poutine in politics:
Poutine is a fast food staple in Canada; it is sold by many fast food chains (such as New York Fries and Harvey's) in the provinces, in small diners and pubs, as well as by roadside "poutine trucks" and "fries stands". International chains like McDonalds, A&W, Kentucky Fried Chicken and Burger King also sell mass-produced poutine across Canada, especially in Quebec. Popular Quebec restaurants that serve poutine include Chez Ashton, Lafleur Restaurants and La Belle Province. Along with fries and pizza, poutine is a very common dish sold and eaten in high school cafeterias in southern Ontario. It's also a very popular meal at ski resorts.
In a segment on the television series This Hour Has 22 Minutes during the 2000 American election, Rick Mercer convinced then-Governor of Texas George W. Bush that Canada's Prime Minister, Jean Chrétien, was named Jean Poutine and that he was supporting Bush's candidacy. A few years later when Bush made his first official visit to Canada, he joked during a speech, "There's a prominent citizen who endorsed me in the 2000 election, and I wanted a chance to finally thank him for that endorsement. I was hoping to meet Jean Poutine." The remark was met with laughter and applause.
"Poutine", pronounced identically, also happens to be the French spelling of Russian president Vladimir Putin's surname, which has given rise to some jokes and wordplay.
