My mother owned a meat grinder that to my knowledge was never used to grind meat. I'm not sure why she acquired it, but at some point in my adolescence it got to be used for cranberry-orange relish. When my sister and I departed home for our own kitchens, we both noted that cranberry-orange relish made with other kitchen implements wasn't quite as good as the official home version. We tried chopping up the fruit in Cuisinarts, or with knives on cutting boards -- close but no cigar.
But it makes the perfect relish. I couldn't do a holiday without it.
