I got a small OXO food mill for my wedding, and it's one of those things that you kind of roll your eyes and snort at until you actually use one.
That thing is great! You wouldn't think it, but I seriously use my food mill probably three times a week.
I mean, I cook a lot, but still, I don't know what I'd do without it.
Now I've updated to a stainless steel food mill, which I would definitely recommend.
This article really has it right -- when you're buying a food mill, read reviews. You really need to get a good quality one, or else you'll be tearing your hair out.
I'm glad that I was fortunate enough to start off on a good one -- now I'm hooked!
