For Mothers' Day I made osso buco. I think I've only made this dish four other times in my life, but it's always good. It looks like a fancy restaurant meal, but it's not particularly difficult to make, although it is pricy and labor intensive.
For the sides I made risotto alla milanese and glazed carrots. The other four times I made this dish, these were probably the accompanying sides as they compliment the osso buco well.
I guess the dish is pretty impressive though, since most people don't eat veal shanks all the time.
