SDMoose is blogging about 70s food. While many aspects of culture, music, movies, style of dress, strike me as having a uniquely 1970's flavor, I hadn't given food much thought.
[Tick, tick, tick] Now that I've given it 3 seconds, here is my thoughtful addition to the list: Fondue. Hard to believe I made it through the decade (corresponding to my ages 8 - 18) and never touched Fondue. Still haven't.
Oh - and I agree with Mr. Moose: I like potato salad and cole slaw. Didn't ever think of them as 70s food, in fact they must go much further back than that. Of course we Minnesotan's never stopped eating them.
