I'm having a hell of a time figuring out what amount of fat gets cooked out of 4oz. of Kroger 80/20 ground chuck....I'm assuming protein stays the same. I cook it in a pan, with a tbsp of canola oil (14g of fat). I know on the package it says 23g fat per 4 oz. raw....about what would this be cooked? I was thinking I might have made up for the fat loss from the beef with the canola oil I added?
