I will definitely ask you for advice when I muster up the courage to buy lamb/pork/calf heart
My butcher sometimes slices veal liver into thin fillets, about 0.5 cm thick, which I sear like a steak - hot pan, butter, 2 min per side. It was pretty delicious - a little sear on the outside and juicy on the inside.
We all made such drastic changes in our diet, keto and carnivore I never ate those greasy meat parts, I would peel parma ham, bacon was no-no…you should see me now
