I dont eat it anymore since organ meats are REALLY rich.
Bad for the cholesterol.
This was 50 years ago, we were poor and we got the liver from relatives that butchered their old milk cows.
The liver had a stronger taste that was different than the typical liver sold by grocers.
Beef sold in stores is primarily steer meat or young bulls.
Almost never cow and even when it is cow it is probably Heffer (Young unbred cow).
