But I don't wanna get sick! Lol I don't normally cook meat but this meat has been defrosting in my fridge for a few days and I did use some of it like a few days back and then refroze it and now I went to make meatballs and it just looks odd! Is it me or is this bad? Isn't the whole thing sposda be pink! When I smell it it smells like raw meat lol so o don't know should I cook this or toss it?
