As a youngster, I used to love it when my grandmother made pickled cow tongue. It was almost impossible for me to wait the time frame recommended before you eat it.
I guess it's a old timey type thing. And, other than on this site where people pickle heart, I don't know of anyone else who makes or eats pickled meats. They also used to sell lamb tongue in small jars in the supermarkets from time to time, and I loved them. You can't find the lamb tongue anywhere these days, not even online.
My kids used to crack up laughing and get all silly yelling, "gross Dad" , as I teased them with a lamb tongue hanging out of my mouth. lol
