I hardly dare to post on this thread. It's like walking on eggshells.
I bought a Nicer Dicer out of curiosity, and it works: it does a dice of about 5mm, but if you put it through again to get a smaller dice, you get puree (French for mush).
I have owned two mandolins. One is a stringed instrument which I would use when desperate to rescue a recording that was going down the tubes (it's now an ornamental object in my parents' house). The other is a fiendish device that performs the same basic function as a potato peeler, but faster, and has the added ability to maim.
I nearly wrote, "Once you've caught your hand on a mandolin you'll never do it again," but actually this is not true because most people keep going for at least another stroke before the reflexes kick in and stop them from maiming themselves for a third time. So be warned - a potato peeler takes only slightly longer, and you'll still be able to play the other kind of Mandolin again.
[I somehow negotiated that without a single reference to spring-loaded choppers.....oops! MATRON!!!!]
I posted on Real Curry Recipes so can you!
