a couple months ago i bought a large beef roast (i think its a round roast), and i cut it into 2 pieces. froze one, and prepared the other. the one i prepared was fairly tough to begin with. now, i have recently found the other half of this roast in my freezer, with quite a bit of frost on it. i thawed it out in my fridge, but do you think there is any way to salvage this roast? should i even try to cook it, or would it be a waste of ingredients? does anyone have a recipe for a tough cut of beef, that makes it more edible? if you could share, that would be great!! thanks so much.
