Shredded Cheese Storage
I just freshly shredded some gruyere and fontina cheese for making gnocchi mac and cheese. I have a ton left over and won't be needing it for now. Any ideas if its best to keep in fridge versus freezer in a ziploc bag and how long will they be fine for in either of those two places?
I’ve done both and have found that shredded cheese kept in the fridge usually lasts a few weeks before getting moldy (especially soft cheeses). Frozen cheese seems to last several months before quality suffers and then there’s the risk of freezer burn. Here’s my little trick for storage. Whenever I get a block of cheese I divide it into 4 oz portions (which equals approx 1 cup shredded). I then wrap those portions in wax paper and freeze in ziploc. Then whenever I need a cup of cheese I just grab a portion, thaw and shred. Hope this helps.
In whatever quantities work for you, put it into zipping freezer bags and suck out as much air as you can using a straw before pulling it out as you simultaneously finish the closure. Or use a vacuum sealer. The cheese will remain mold-free for a couple of weeks in the fridge, or good for many months in the freezer.
home-shredded cheese does tend to go moldy more quickly than blocks because it has dramatically greater surface area. cheese freezes very well and as others have suggested, freeze it in portions that are good for your future needs.
I keep a tightly-lidded plastic container of shredded cheeses in the freezer at all times-when it starts to deplete, I grate whatever is looking tired in the fridge. This is my 'go-to' savings for some mighty fine macaroni and cheese dishes. The exact mixture depends on what the family has been eating, but always cheddar, swiss, parmagiano and 'blue' (the latter in moderation, either a crumble of roquefort, Maytag or gorgonzola).
This may sound somewhat random, but mac'n'cheese bound with a good bechamel and spiked with English Dry Mustard is very forgiving...
