I'm relatively new at using my US&G and am wondering what the best way is to julienne food, especially carrots. Couldn't seem to get it to work easily, without a lot of elbow grease. I know this isn't how it's supposed to work, and I'm sure it's I, not the product. Any tips on this--I want to demo it at my next show and want to be confident about it. I'm finding that the food holder doesn't seem to be big enough to hold the food I want to slice. I've heard that some people start out without the food holder, but I'm a little afraid to do this--eek!
