>>100053541American parents just don't know how to cook
After years of being indoctrinated by fad diets, they now avoid simple things like salt and bread
A lot of terrible cooks stem from periods of time where food tasted bad because we didn't have access to good ingredients, whether through rationing or just lack of proper refrigerated transportation
My own parents rarely used salt, cooked all of their meat well done, and barely used the oven.
Roasted broccoli is 10x better than boiled or steamed IMO, yet they never actually tried to improve their cooking.
