Flash freezing has been done in the food industry for ages to quickly preserve and seal in nutrients and freshness. It’s why nutritionists say frozen seafood, vegetables, and so forth are technically “fresher” than their fresh cousins you find in the grocery store.
Of course, if you’re practicing locavore-oriented shopping, you don’t have that problem now, do you? It’s not hard, and you don’t have to be a hardass about it. You’re just growing a garden, or befriending people who do, or participating in a CSA. Okay, I had to act like I knew what a CSA was. Hey look, it stands for Community Supported Agriculture.
Oh, wow. There’s one in my area. Crap, now you know where I live. No stalking!
Back to locavore stuff. You’re doing the above, and/or you’re looking for locally-grown produce at the supermarket, you’re befriending people with chickens for eggs, etc. It doesn’t have to be all intensive like the people who do “we’ll only eat anything grown within 100 miles” experiments.
So if you’re me, one locavore thing you’ve done recently is go to a local orchard and buy or pick blueberries. You picked a lot of blueberries. And you might as well throw some in the freezer for winter.
There’s something sparkly about pulling berries out of the freezer in the dead of winter, and making a smoothie, or cobbler, or pie. In like, February. You want to do this with your pretty local berries.
Note: This method can be used with nearly anything solid. I freeze tablespoons of tomato paste this way. Adobo chiles. Some people flash freeze lemon slices, or mushrooms. I don’t know if I trust frozen mushrooms, but they can’t hurt if being thrown into a lasagna or something. Read more on how to flash freeze blueberries…
