I make my own marinara sauce but have always used canned tomatoes, I also make berry jelly but don't care for seeds. I bought this (already had the grinder which is required) and immediately ran 15lbs off Roma tomatoes through it. No peeling or seeding needed - just quarter the tomatoes and shove them through. Voila, 9 quarts of tomato sauce (very runny, took 8 hours to cook down, but excellent! ). I made blueberry/raspberry/blackberry jam yesterday - just dumped the fruit down the chute and instantly had beautiful, seeded but pulpy fruit juice which made the best jam I've made yet. Can't wait to try homemade applesauce next.  Cleans up quick, too (I handwash all my Kitchenaid parts).
