I didn't know avocados can be frozen. How do you do it? Whole?
I buy them by the bag at my Costco Business Center. They're already peeled, halved, pitted and frozen. Very inexpensive at 3 pounds for $8.99 and they're at perfect ripeness.
The texture isn't ideal, but these avocado halves are excellent for recipes where the avocado is pulverized in a blender or food processor anyway. They're good in smoothies or whirled avocado/bean dip recipes that don't rely on chunks of fresh avocado. They don't turn brown (ingredients are avocado halves and citric acid).
I find them to be a good adjunct to fresh avocados, for instance as the primary base for guacamole, but it's best to also add some chunked fresh avocado.
I also meant to say that I often have
frozen mushrooms in my freezer. I buy whole or sliced mushrooms on sale, dry saute them, drain the liquid, then freeze them flat in ziplock bags.
Another trick - once a year or so I buy a container of whole peeled
garlic, mince it in a small food processor with some olive oil, then freeze it flat in about 1 cup portions in ziplock bags. I break off chunks when I need garlic in a recipe. I do the same thing with leftover fresh
cilantro - otherwise it gets slimy in my fridge in about three days.
When it comes to cooking, I'm very big on doing things ahead as you may have surmised.
