One of the main problems with the Kitchenaid grinder is the proprietary grinder plates that go with it (standalone grinders use standard plates that come in a billion sizes). There are really only 2 sizes...."fine" and "very fine". The "fine" grinder grinder plate is 1/4", which is pretty good for many salami, the "very fine" is not particularly useful except for a few things. So I had a friend in a machine shop make me a larger 7/16" plate (someone on ebay makes them, take a look there, they're a great deal at $15 a piece). It works really well, but it's a just a HAIR too big. The other day I checked out Ebay to see if anyone had made any other custom plates, and imagine my surprise when I ran into a Kitchenaid "coarse" grinder plate, which didn't look like my "coarse" grinder plate!
It appears that at some point, quite a few years ago, Kitchenaid decided that for home use, a 1/4" coarse plate would be more useful than the one they had back then in the kit, a 3/8" one. I would agree that 1/4" is more useful for stuff like burger...but 3/8" i think would be nice to have for salame. I got it for a bargain $12!
Here is the plate I just got in the mail. I think it'll be a perfect size for many salami...excited to use it.
My advice to all those with a KA grinder is to keep an eye open at thrift stores, flea markets or Ebay for an old style "coarse" Kitchenaid grinder plate.
