Why Are My Frozen Potatoes Soggy?

Q:

Could you please tell me why when I thaw out last year’s bag of frozen potatoes they are holding a lot of water and are very soggy? We blanch, cool on a baking sheet and then freeze in bags but they are sooo soggy. Please advise.

A:

It is hard to get all of the water out of a potato as one potato normally has over 80% water to begin with. Processors flash freeze the potatoes as individual pieces, not possible at home, although you could try to separate the cooked potatoes on sheets for the first attempt at freezing next time and then combine and freeze for an extended period.
