How do you prepare water chestnuts?

[Guest guest]

Hi everyone, my sister in law has 8-9 chestnut trees in her backyard and I'd

like to use them

to bake cakes and other things, but have no idea of the best way to " mass

produce " a paste.

Do I put them in the oven and then peel and mix? should I leave them as such

for future use?

Do I freeze the paste or best can them?

Any expert cook advise welcome! It will be a nice change from the nut flowers,

most of all for

my pocket! ($$$$)
