Debbie, Publix has rather nice calf's liver in the frozen foods dept, about $5 for four 4-oz individually wrapped slices. I used to buy two packages at a time, when I lived in Florida.

Best way to cook a slice is to plop it frozen into hot butter, cook a minute or two until browned, then flip and cook the other side until just rare. Mere minutes until on the plate... overcooked, tough liver is disgusting, lol.

Cooking a frozen slice also means it keeps its shape better for flipping, as well as preventing overcooking.
