The point is more general than cooking. Clearly if you hate cooking, it's going to negatively affect how you feel about your efforts cooking. But the point still stands. Putting in effort to achieve something you want will very likely make you value it more. I built a new shower in my master bathroom - it's easily my favorite shower now because I made it. I built a road bike from individual parts, and it's my favorite bike, even though it's heavier and uglier than other bikes. I raise my kids every day, and I value them more than other kids, etc...
