Water chestnuts have a lot of water in them, so the rate at which they are frozen
will be a critical factor in their quality when used. Since it looks like you're at
a University, try to find some liquid nitrogen (try the Chemical Engineering, or
Material Science departments). Bring a thermos. Be careful with it, cuase it'll
burn you pretty bad if you touch it with your skin (just 'cause it's -70 Celcius).
Get some lab goggles and some thermal mits. If you can work it out, it could be
pretty fun. Dunk them in for a few seconds (about 5 to 10), then put thhem into a
bag that you will put into your freezer.
By freezing very quickly, you will keep the ice from crystalizing; it will solidify
in what is called an amorphous, or glassy state. Since few ice crystals will form,
the tissue of the product should remain pretty good.
