What are the disadvantages of frozen food over fresh food
You have to keep it frozen till you use it. Once it thaws, even if you refreeze it, it will begin to lose flavor. Also, when you ARE ready to use it, you have to wait until it thaws before you can cook it.
Besides taste? I personally enjoy the flavor of fresh food over frozen food.
It's texture is much better when fresh
I use frozen veggies like spinach and broccoli often. Very good.
