Thats because Halal meat and tesco bought or shop meat is different it is served much more differently, the way its slaughtered means all the blood is completely drained from the meat before its packed so you'll never get a blood puddle when you defrost it hence the change in colour, because of lack of blood and water which they use in supermarket meat and you won't find non blood meat in a normal butcher either, this meat is the healthiest you'll get as someone who eats only halal meat, I can't stand GFC however her meat choice isn't vile,the pool of blood out a tesco pre packed chicken is vile. And other cultures cook differently, so the meat looks vile only to those who are not educated on the meat they buy and why its that colour and is I fact far better than what they buy.
