I like to freeze my spinach and use it in smoothies. When I bring it out of the freezer, I crush it as much as I can. I then measure it out in 2 cup quantities. How much would this equal in fresh spinach. Thanks in advance.
Best to use a scale. Measure how much fresh spinach you normally use and use the same weight for frozen. Moisture content for frozen spinach may be slightly less than fresh but it should not matter that much. There are very few occasions when volume measurements are actually necessary and a weight measurement is not appropriate.
