I work with a kid who really likes cold sensations in his mouth (autism, this kind of experience isn't uncommon.) At snack time he eats frozen peas and frozen blueberries.

Which is why when I recently cooked with frozen peas, I tried a few before cooking. I get it, I'm a fan of peas and the novel texture of them being frozen was interesting. I didn't love it enough to make a new snack out of it, but you're right - you never know until you try.
