I've been curious about a flavor that's in a lot of SF's deep fried goods. I've never tasted it in a restaurant, but you sometimes get it in doughnuts, and it's overpowering in the deep fried piroshki you find in delis. It's certainly in Paramount Piroshki's products. Anyone know what type of oil it is? I haven't ruled out rancid oil, but it doesn't exactly smell like the rancid smell you get in old canola bottles or most packaged foods gone bad.
