The canned food companies have changed recipes many times over the years. Recently a lot of brands have dropped sodium amounts.
I noticed that kraft had changed their recipe a few months before they announced it and said that people couldn't taste the difference.
I've always hated that bit of smarketing cowpoo, I can always taste the difference.
Two foods I loved as a kid but make me want to puke now are corned beef hash and cocktail weiners.
Kid me was bless'ed weird.
Still can't stomach fish, and don't care for mushrooms.
But yeah, anything with a tomato based sauce tastes wrong now.
