It isn't pink goop. It's more like a beige-ish sludge. Gross? Not entirely because ground up raw chicken meat made on a mass level will probably never look appetising, no matter how clean the process and how delicious the result is. But at least it's good to know you're not eating alien meat?
McDonald's Canada recently addressed what's actually inside a McDonald's Chicken Nugget and it's not as exotic as we were afraid to believe.
It starts with a whole chicken which is sliced up and separated into their specific cuts. Chicken breast is separated and collected into a bin. The bin o' chicken is then ground up and chicken skin and seasoning is added to a meat blender. The blended chicken is then shaped into the four official chicken nugget shapes and dabbed with a light and heavy batter. It doesn't exactly look good when it's made (as you'll see below), but it's still chicken.
